Shellder
#138 in the Ultra Sun & Ultra Moon Pokédex • Bivalve Pokémon
Ultra Sun
The sand that accumulates inside its shell eventually becomes a pearl. But the pearl gets in the way, so it spits it out and discards it.
Ultra Moon
Even when its shell is closed, its tongue still hangs out. If you give its tongue a good yank, the shock will cause Shellder to open its shell.
