Does Slowbro really have a Shellder on its tail?

Question

It says that there is a Shellder as its tail, however, looking at the Pokedex it looks nothing like a Shellder.

Answer 1

Game Freak wanted it to be like it. I'll edit this if I find something.

Found something.

>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.

Shellder changed it's shape due to having a mutual relationship with Slowbro.
