I think it is unlikely for her power to make pop-cultural references in order to explain / describe objects or substances. Yes, power may recognize when someone is making such a reference in a dialogue, allowing Tattletale to connect the dots, but it won't be primary form of expression to explain things, it will rely on neutral statements instead (not intentionally poisonous, meant to drink, no directly consumed by game producing it...)
You know, if canon didn't give us an interlude where her power presented information in stream-of-consciousness words, I'd posit that it's more likely that where her power ends and her own logical leaps begin would be harder for her to identify. The mass of intuition about "intended to drink to restore unknown energy" + "blue like windex" + "half-remembered bit from Alec's video game" = "mana potion" would just all come together so she jumps to the conclusion without really puzzling all the lead-up out. If she really wanted to, she could trace back to what each bit that led to it was, much like many humans can with their own intuitive leaps...sometimes...but she just gets conclusions. Because it's intuitive.
This is how it worked in Heromaker's Legacy, and, IIRC, also in Mauling Snarks.
"Hey, Tattletale, this is your new costume."
To be fair, it is a cut-rate Venom suit.
Looks like it. So basically order the Symbiotic Oooze to follow TT's command? I think TT will be getting a suitcase or backpack soon, unless it can just hide under clothes. And maybe even then. Even if 'protection against getting shot dead on the street' is a NICE perk.
So anyway, TT probably don't want to wear acidic slime, even if it gives immunity to acid while being worn. All it takes is a little getting stuck on the clothes, it gets off, immunity to acid goes away... ouch. All the ouch. So. Alternatives to acidic is 'other elemental properties'. Hmm. What would that be? Silicone/Lightning? Sulphurous/On Fire? Water control? Water cannon? ..actually, that last one could be both rather useful and appropriate.
Hmm, I ran across an image on deviantart a while back that could serve as a elite/evolved version of this beastie.
No, FAKE pit trap with a tarp cover that is imperfectly painted to look like regular floor, so the intruders think there's a trap when there's only ordinary floor under it. The real trap is the slime in the much better camouflaged CEILING compartment!
Turns out the visitor's room is also slimes. Cake Slimes.
Now you just want someone to write "The Cake is a Lie!" on the wall underneath that sign. In their own blood. You monster!
actually, there should be more possible earths but there aren't and that's because of the entities. they collapse alternate possible earths into groups because a conflict with an earth to similar to your own won't cause new data to be acquired.
this right here was my thought too. when i saw the drop coming i was already thinking. "you're too late you can't break a magical contract with shard BS because entropy breaking magical BS trumps space whale pseudo-magic."
