Bivacle is a Water/Rock-type Fakemon that appears in the fan game Pokémon Obsidian by Atomic Reactor.

It evolves from the Pokémon Shellder, and evolves into Cuttacle starting at level 36.

Dex Entry Edit

Once a Shellder clamps on to a Slowpoke's tail, the nutrients in the tail trigger an alternate evolution for Shellder.
