I'm literally imagining a carp jump out of a pool and into a nearby set of samurai armor, then transforming into its human form and running off to go fight some spider people and their umber-hulk slaves.
the carp samurai probably make a game of this; its considered the acme of skill to leap into your armor at the right angle so you can instantly transform and run off to fight. its more embarrassing when you miss your mark and have to flop around until you can get into your armored coat.
