The Mollusks worked for Eel Capone for a time as his "hired mussel" to do his dirty work.
When they came across P.B. Jellyfish, they would have almost killed him if wasn't for the rest of the Forty Fathom Freedom Fighters (except for Big Fluke who was migrating). The Mussels were killed by Bottlenose who was disguised as a ninja as they were dropped in a deep hole, where the underwater pressure killed them instantly.
