What little you have as a plan can be summarized as this: Get in, get a shovel, get out before Puppetmon realizes you're here. Failing that, get out before he can properly react to your presence.
Yes, you're aware it's not the best plan in the world. It's all you've got, though, so you're going to stick with it.
You search for a door that doesn't have any minions surrounding it. There's one, off to the side, but it's closed with a padlock of some sort.
"Biyomon, do you think you could break it off?" You ask.
Your partner doesn't flutter away from your spot in the bushes, but you can see that she's thinking really carefully about it. "...Maybe," She eventually decides. "And I wouldn't have to Digivolve for it. But if someone finds it..."
"They won't necessarily know that we were here," Rikuto points out. "Just that somebody was. And that somebody could be anyone in this forest."
Left unsaid is how you haven't encountered any Digimon in this forest that haven't thrown their lots in with either Elecmon or Puppetmon. There's not really a lot of places to look, unless he means to imply that Puppetmon doesn't actually trust his minions all that much. But if that's the case, why even keep them around?
"...It's that or we find another way in," You finally admit. "Let's try it."
You all hurry across the clearing as quickly as you can, glancing around. You don't see any signs of Digimon around, just the three of you. It's... really creepy.
Then again, maybe that's just what happens with mansions in the middle of the woods. It's sort of like the Overdell, this way, except that you aren't sure the Overdell fits Puppetmon's aesthetic. You certainly haven't seen any Bakemon around.
Biyomon breathes a steady stream of green fire. It pierces the lock, and it clatters to the ground.
It also blasts a small hole in the door. Fortunately, the flames don't do much more than smolder, so it'll probably be safe to go inside the building.
You enter into a room that is completely dark, the door swinging itself shut behind you. You can't even complain about that last part, because the only thing more damning than the lock being gone is you accidentally leaving the door open.
Still. It'd be sort of nice if you could see.
