He is a dual-type Water/Psychic Pokémon introduced in Generation I in the Pokémon Series. Slowpoke first appeared in R64: Freddy's spaghettiria. He appears trick-or-treating at FightingMario54321's house, only for him to slam the door on him because it wasn't Halloween anymore. A frustrated Slowpoke is then run over by Mario driving his kart. A Slowpoke works as a bank teller as shown in SMG4: Mario Waits in Line For Some Spaghetti, though it could be a different one from the one in Freddy's Spaghettiria.
Slowpoke is a pink Pokemon who greatly resembles a platypus. He has a pink body, a tan-colored muzzle, curled ears, white toenails, and a white-tipped tail. It goes fishing with its tail in the games, and can't feel pain. People also seem to think that its tail tastes good.
