Hit me, please!
Mario and co. must travel to Rogueport Square, where Mario must use his hammer on Mousimilian to help him remember what he forgot. If hit after he remembers, he will forget again. If talked to after he remembers, Mousimilian will state what he was trying to remember: Sleepy Sheeps cost two coins less in Rogueport than in Petalburg, meaning a two-coin profit can be earned by buying a Sleepy Sheep in Rogueport and selling it to the shop in Petalburg. Unlike the other Trouble Center missions, Mousimilian does not reward Mario, citing that the tip is enough.
