The Shell Crusher is a minor antagonist in Turbo. In the beginning of the film he was shown riding his trycicle scaring the other snails. Later when he saw Turbo, they fought against each other as Turbo won against him, and the Shell Crusher is seen calling for his mom and bumping into the door. Then, as the snails supported Turbo on the window watching the Indianapolis 500, he is seen again calling for his mom again and bumped into the wall. Later at the end, he redeemed himself by picking out new shells for Carl and some of the other workers at Bobby's Hobby Shop.
