The Lobster Mobster is a lobster gangster in the style of a stereotypical gangster of the 1920s. His sidekick is Da Shrimp. They are minor villains who only appear in the episodes Urchin, Double Bubble, and Thingamajigger in the TV show, The Little Mermaid. In their last appearance, they get chased by a thingamajigger (a pirate's boot).

The Lobster Mobster also appears in the game Disney Adventures : Sport Goofy Olimpic (released as a Game Boy and Panasonic 3DO, published by Konami in 1994).
