Snackeral

The Snackeral is an enemy in the game Wario: Master of Disguise. Snackerals appear only at Sweatmore Peak during Wario's adventure through there. Snackerals appeared alongside Battle Salmons, an enemy that first appeared in the Smithsnorian Museum. These fish appeared smaller than the Battle Salmon and are pink in color. If Wario manages to come in contact with one of these fish, they'd take his Sweatmore Hotpants/Superhotpants and run off. If Wario is in lava and he doesn't have Hotpants, he's going take damage until he gets out of the lava or until he gets a Game Over. Alternatively, he can transform into Dragon Wario. Should this happen, a nearby red chest will always turn purple and contain a replacement set of Hotpants.

In-game Description
''This fish has been turned into the ultimate weapon by unethical scientist-types. In its spare time, it enjoys war films and sushi.''
