Spiny Cheep-Cheep is a spiky blue Cheep-Cheep species enemy that first appear in Super Mario Bros. 3. They overall have the same abilities and traits that normal Cheep-Cheeps can do, but have spikes on which does not make a huge difference as Mario and Luigi cannot attack underwater enemies in regular ways. These enemies reappear in Super Mario Land 2: 6 Golden Coins as underwater enemies once more and were colored black due to the Game Boy's color limitations. It acts similar to how it did in Super Mario Bros. 3.
