Goal?

From my memory, gru went in to sabotage the guy who scammed her. But this dungeon is different from other ones where you have to complete the goal it gives you to get out. Almost like a role play thing. But if you don't meet the requirements then your all stuck and I think it will explode. ..I think

Dungeon plot is basically the world is corrupted (basically pollution) and the snow leopards (the strongest beastmen) are the ones fighting back the corrupted beings while the squirrels are the ones growing the acorns to stop the corruption (but somehow they’re considered lower-class citizens) and only the flying squirrel can grow the golden acorn which can reveal the dungeon heart to finish the dungeon (from what I remember/understand)
