Some suggestions and ideas....
Head.
Eyes:
1. UV Vision (Already Available as a ?, meaning you are to young for it.)
(Expanded Range of Perception)
2. Magnetic Field Vision (Also already a ? but good thinking out of the box.)
(Like Pigeons)
3. Pressurised Blood Jet Shooting (Not a very good idea, would just attrack every predator for a couple miles to come and eat you.)
(Like some Frogs etc)
4. Thermal Imaging Vision ( I swear we must be thinking on a similar wave length, as this is also a ? option)
(A variant of both IR Vision and Heat Pit Sense of Snakes)
Nose:
1. Extended Proboscis (I'm not sure why you'd want this?)
(Nose extends from the Face, the Nostrils now more Mobile like a Rapier)
2. Trunk (Your tonge already does most of this, and it really breaks my idea of a dinosaur, so not an option.)
(Like an Elephant, Prehensile and able to grip physically, also able to blow air and liquids and suck them, for self cleaning, play and utility)
3. Femme Fatale (See the reason above.)
(You can now strike Prey or a Foe with a Needle like probe that can retract or extend from the Trunk, letting you drink Blood of those you strike! Like a Vampiric Mosquito!)
4. Gunnery and Tools (See reason above.)
(Can now blast out Liquids at high pressure to knock over and injure Prey or Targets of Humour, can Dry things fast now, can also refill on Liquids and Air rapidly)
5. Bifurcated Trunk (See reason above.)
(The Trunk has now split, two trunks instead of one, one Nostril per Trunk, you also get a second Vampire Needle)
Mouth:
1. More mobile and dextrous Lips (Good idea here, I'll add it to my list as lip dexterity.)
(Able to alter sound better, can also now Spit better and further, more accurately too)
2. Improved Adhesive Spit (I'll have to think about this one.)
(Able to use Saliva to stick things together more strongly and for longer, can also use as a Trap method by tongue deploying Saliva to surfaces, objects etc, this can deny usage of objects, provide area denial and divert targets by redirecting them to avoid it, bind targets/prey to objects or surfaces, can seal open wounds, secure and prevent access via windows and doors etc by jamming them shut, block locks to deny key usage etc too)
3. Medicated Saliva. (Your saliva already does do the cleaning stuff although to a lesser degree, another thing to think about.)
(Saliva now promotes healing and has disinfectant qualities to clean wounds etc, can work with Adhesion to seal wounds quicker, clot blood faster etc)
4. Prehensile Tongue (Nope, just all the nope.)
(Not only can you shoot out and retract your tongue to catch Prey, now you can use your Tongue like a Tentacle to manipulate everything with!)
5. Toxic Saliva (Another thing to think about, really stop making me think. My brains going to explode.)
(Still safe for Azula and Sister, but now dangerous to anything else, more effective if exposed to broken skin or ingested, in contact with eyes etc)
6. Slippery Saliva (I'm gonna say no to this one as well.)
(Can now swap to a Slick Saliva instead of Adhesive, can be used to make Traps etc and to aid swimming as well as retain heat when in water)
7. Acid Loogie (Nope, nope, definitely not. Joking aside this is already a ? option)
(Saliva can now be Highly Corrosive, able to cause Chemical Burns and even Dissolve things in larger amounts)
8. Alchemist (It's a no for this one.)
(You can now Secrete each of your Four types of Saliva, able to mix them for different effects, or spit them out seperate to meet and combine at a distance for more potent and destructive chemical reactions that you do NOT WANT happening inside your Body.... Accelerant, Combustible, Explosive, Gaseous effects etc)
Body.
Skin:
1. Shark Skin Style (Huh, I'll get this added as Shark Skin.)
(Skin is now hooked and bladed on the microscopic scale to vastly improve swimming, as well as being rough to the touch like sand paper,easily able to injure those foolish enough to get close)
2. Sun Touched (Already have a similar ? option.)
(Can now soak up energy from the Sun, like a Jellyfish does with it's Symbiotic Bacteria or how a Plant does so, can gain nourishment via Sun, reduce need to eat as often and can heal better in the Daylight if not Hungry/Starving)
3. That's Shocking! (Another ? option.)
(Skin can now build and hold static charges that can be released when in close proximity or touching Prey or Targets, this Electric Effect/Attack is made more powerful and can hold more charge if also have Sun Touched)
4. Bioluminescence (An effect that will either occur from Prototype points, or a ? option.)
(Can now use Hormones and Biochemistry from Cuttlefish DNA to Glow, use different Colours of light, confuse prey, stun prey, hypnotise prey, also improves Camouflage even if still Pixelated, though far better if Pixelated is removed, can also Shine/Glow brighter if have That's Shocking)
5. Heat Exchange (Pretty good Idea, I'll get it in as a ? option)
(Can now radiate intense and even painful heat as a defense, or if need to cool down in a hurry, or can now absorb IR Light which improves Sun Touched and boosts energy available, also can be used to alter Heat Signature in Thermal Output to fool Creatures or Technology to seem smaller or of a different shape and animal, better Thermoptic Camo/Masking if also have Thermal Imaging Sight)
6. Secreting Glands (I'll have to think about it.)
(Can now use a Sweating type effect to coat the Skin in Adhesive or Slick Secretions, to aid in catching Prey, assist in climbing or carry loose objects, or to escape entrapment or make an enemy unable to grapple with us)
Heart:
1. Internal Adrenaline (Another thing to think about.)
(A Boost for Combat or Urgent Situations and a last chance jolt to force our Heart to start beating again if stopped)
2. Complete Control (I'm gonna say no to this one.)
(Now able to accelerate or reduce beating of heart rate if wounded or if want to fool observers to think we are asleep if awake, or seem dead if needed)
3. Second Heart (Nope.)
(Big Boost to everything as well as providing a back up if our Primary Heart is damaged or destroyed etc)
Lung:
1. Gas Mask (Already have a similar ? Option.)
(Filter out Toxins, particulates etc to keep functioning in air that is toxic and or dangerous in other ways)
2. Pat on the Back (Nope.)
(Have additional Lungs to improve both oxygenation efficiency and to store an Air Reserve to extend held breaths)
3. Blow Hole (I don't see how this would help avoid drowning.)
(Like a Cetacean breath through your uppermost part to avoid drowning while swimming)
4. Snorkel (Nope, cool out of the box thinking though.)
(An extendable tube with a inflatable bladder that will rise to the surface of water while allowing most of the Body to still Swim deeper below)
5. Gills (Already a ? option, pretty expensive too.)
(Self explanatory)
Bones:
1. Lightweight (Another ? option.)
(Bones are now hollow to reduce weight, improve speed and leaping/jumping)
2. Honeycomb (Good thinking, I'll add it in as a ? option.)
(Still Hollow, but now much stronger and more durable)
3. Subdermal Armour (I'm gonna say no to this one.)
(Bone Plates and Meshes now grow below the Skin, providing better defense against Piercing and Slashing attacks, Vital Organs gain a Sheath of flexible bone and muscle to protect them more fully)
4. Fully Wired (Gives me something to think about.(
(A Secondary Nervous System as well as a set of Electric Sacs throughout the body all provide better reaction times, muscle twitching and provide more Electrical Energy for many uses)
Digestive System:
1. Flower Power (Already a similar ? option.)
(You can now gain nutrition and energy from digesting plant matter)
2. Eat like a Pig, break it down like a Hyena (Already a similar ? Option.)
(You can now safely eat rotting and toxic foods both meat and plant based, digesting even bone and leaving only Hair undigested)
3. Probiotic Yoghurt! (Hmm.)
(You now have super charged Symbiotic Bacteria that aid in breaking down even inorganic matter, on top of which they even seem to have boosted your Mitochondria's energy retention and transmission!)
Limbs.
Arms/Hands:
1. Venom Claws (Similar ? Option already available.)
(Your Class now can Secrete or Inject Venom into your pretty or Foes)
2. Acid Strike (Reason already stated.)
(Melt enemies in their wounds and foul healing)
3. Pile Driver (no to this one.)
(Blood Pressure can now make a Forearm length Claw/Sting that can be Fired out from below the Wrist from the hand at extreme speed and force to deliver massive damage)
4. Finger Guns (No to this one as well.)
(Blood Pressure can now be used to Fire your Class on your Hand out like Darts for a Ranged Piercing attack, they can also deliver Secreted Payloads)
5. Edgey as Fuck (Amusing thought, but no to this one as well.)
(Your Wrist Pile Drivers now have cutting edges allowing their use as Bone Swords as well as being Piston Spikes)
Legs/Feet:
1. Moon Bounce (Already have something with the same effect.)
(Your Skeletal and Muscular arrangement in your Legs now is similar to that of a Kangaroo, this allows you to Recycle Kinetic Energy to use less energy and to enable Longer and Higher Jumps, they also give you a faster overall movement Speed)
2. Knees that Sting better than Bees! (No to this one as well.)
(You now have a Pile Driver Spike like the Wrist Mounted version, it emerges from the Knee for an even stronger and faster effect)
Tail:
1. Must Crush Capitalism.... Lol (Already an option with the right mutations.)
(You can now use your Tail to pick up bigger creatures and things, you can CONSTRICT them! Like a Boa, but not the Feathered kind.... Still no good for delicate or dextrous tasks though, clumsy for anything except lifting and crushing)
2. Tale with a Sting (Available as a ? option.)
(You can now use your Tail like a Scorpion's, as it too has a Stinger on the end, with which you can inject Prey or Foes with)
3. Squirter (No.)
(NO NOT LIKE THAT YOU FILTHY ANIMALS!!! You can now Spray a range of your differing bodily made liquids from a variety of different nozzles, with greater range and power, you can also stagger shots to get combination reactions on the targeted location)
4. Waste goes over there! (No.)
(Your Anus has migrated to your Stinger away from the rest of your body, making you both cleaner as well as making your Stinger more Deadly, if you think a Monitor Lizard's mouth is bad.....?)
