Slowbro (Japanese: ヤドラン Yadoran) is a dual-type Water/Psychic Pokémon. It evolves from Slowpoke starting at level 37. It is one of Slowpoke's final forms, the other being Slowking.
Slowbro are physically slightly different Slowpoke. It now has striped, tan belly, three claws on its forepaws, and two claws on its hind paws. It has a Shellder latched to its tail in a symbiotic, almost parasitic relationship. The extra weight on its tail has caused the Slowpoke to become bipedal. As a result of carrying this burden, its special abilities have developed greatly. Through the symbiotic relationship, the latched Shellder grows in a spiral shell instead of a bivalve. If for any reason it loses its Shellder, it will result in the Slowbro returning to its former Slowpoke self.
