Snailicorns[1] are large snail-like enemies in New Super Mario Bros. Every Snailicorn has two small green feet and a horn on its head, and their name is a portmanteau of "snail" and "unicorn." Snailicorns appear in only two ice levels, World 5-3 and World 5-B. A Snailicorn walks straightforward on the platform it is on and turns around to avoid edges if necessary, similarly to red Koopa Troopas. If a Snailicorn sees Mario or Luigi, it charge in a straight line and tries to attack with its horn. Though Snailicorns cannot be defeated from being jumped on or from a fireball, jumping on a Snailicorn's shell pushes it backward, possibly into gaps within platforms or bottomless pits, and Ground Pounding a Snailicorn pushes it even farther back. Snailcorns can be defeated from either Shell Mario's Shell Dash move, a Mega Mushroom, or a Starman.

The game's internal filename for Snailicorn is a romanization of the Japanese name for Bully, suggesting that it was originally designed as one before being changed to a horned snail.[2] This explains why the two species act in a similar manner. Given that it has one horn and only appears in ice levels, it may have specifically been modeled after Chill Bully.
