Crowber

Crowbers, also simply known as Crows, are bird 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.

New Super Mario Bros.
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.

New Super Mario Bros. Wii
Crowbers reappear in the game New Super Mario Bros. Wii. They are redesigned with a purple plumage and a lighter beak and legs, and appear in and World 8-5. They attack in the same manner as they did in New Super Mario Bros.

New Super Mario Bros. 2
Crowbers reappear in New Super Mario Bros. 2. They appear in, World 6-4 and in the first level of the Impossible Pack. They maintain their appearance from New Super Mario Bros. Wii. In the first of these levels, they always follow a preset movement pattern due to the automatic running, unlike their normal random movements.

Dr. Mario World
Crowbers make their debut in the Dr. Mario series in Dr. Mario World as obtainable assistants. In this game, they revert back to their black coloration. In stage mode, its effect is to increase the amount of capsules the player start with by one, where the chance of it happening is greater at higher levels. In versus mode, its effect is to reduce the speed the attack meter fills for both players by a percentage, meaning that the amount of points required to fill up the attack meter is increased by that percentage, rounded down to the nearest round number.

Paper Mario: The Origami King
Crowbers make their Paper Mario series debut in Paper Mario: The Origami King, where origami Crowbers appear as enemies. A single one appears in Scorching Sandpaper West, while three others are encountered on Bonehead Island. During battle, Crowbers will line up behind one another and attack Mario with a Beak Bomber move in succession, with a brief delay between each individual's attack.

Other appearances
Crowbers were originally going to appear in New Super Mario Bros. U, but were not used in the final product. They can be seen, however, in one of many unused stages. As seen in it, they were intended to act and attack like they did in previous New Super Mario Bros. installments.

Crowbers were going to reappear in Paper Mario: Sticker Star, but were cut from the game.

A Toad Quiz in Mario & Luigi: Paper Jam has the enemy's name as one of the answers.

A Crowber is one of the figures in Series 3 of the Character Packs in the LEGO Super Mario line of merchandise.
