Crowber

Crowbers, also simply known as Crows, are raven-like enemies first seen in New Super Mario Bros. These enemies tend to appear in the last courses of the game, where they attack Mario or any other potential victim with rather fast moves. The name Crowber appears to be a pun from "crowbar," a tool used to remove nails.

Crowbers are only seen in World 8-1, where they swoop down to attack Mario. As progress is made throughout the course, more will appear and chase after the player. Crowbers attack quickly, making it somewhat difficult for the player to defeat them.
