They'd function like Pokemon Trainer. They'd switch to have different benefits and move sets.>or try an ice climbers set but I don't understand ice climbers at all so we're going with pokemon trainer.
All three have side Smash Hammer, neutral B bomb throw, Down B anvil throw and same recovery (up B zip like Pikachu) but range and power level is what's different.
Yakko: Long range, medium power level, moderate speed. Jigglypuff like Sing move puts people to sleep, leg sweeps, high jump (moves mostly with hands in his pockets).
Wakko: Medium range, high power, slow speed. Wario's chomp recovery move, pockets items, has a belch waft like wario.
Dot: Low range, low power, high speed. Peach's butt bounce but faster, does a twirling kick that works like a dash move, her sing/kiss move causes a flower to spawn on your head. >suggestions wanted
