Here's the situation: I'm in a room in Mystifying Forest. There is a Stunky near Kecleon's shop. It has Aftermath, and, as some of you may know, Aftermath lets the Pokemon have a chance to explode and destroy items and Walls in the Mystery Dungeon series. Say Stunky blows up a Pack of Iron Thorns. Then what happens? Those things are like level 70 and they're what you'd call EOD/EOT ubers, I've seen them inflict over 400 damage on me.
Nothing, it just gets destroyed.
