Another custom Mystery Dungeon Trap! And it's a classic trap. The good 'ol Treat underneath a box. Though this one is more of a Hinderance than a Curse, but I still think it fits well with my dungeon. The already uncommon item spawns (Outside items are not allowed and apples are the only item potential spawn) in my dungeon really forces hungry adventurers to tempt every Apple. Gotta hope your partner will find you before you feign from hunger, and that they are actually capable of lifting the box. Who knows what other curses might await them.

A little thing that I really enjoy about the box is always much smaller than the Pokémon that triggered it, really condensing them into it and adding insult to injury. I always contemplate just leaving them in the box as the punishment for failing my dungeon when I find them.
