A Shellcreeper is an enemy in Mario Bros. They are defeated in the same way as the other enemies in the game, by hitting the floor below them, and then running into them. They are essentially the precursor to the Koopa. To make it so players wouldn't try to jump on them in the GBA remakes, they were replaced by Spinies.
