Clawgrip

Clawgrip, (originally Clawglip in the ending credits in early versions), is a giant crab and a boss from Super Mario Bros. 2.

Super Mario Bros. 2
Fought in World 5-3, Clawgrip would attack players by using his claws to throws boulders at them. In order to injure Clawgrip, these boulders would need to be caught by the player's character and thrown back at Clawgrip. After being hit five times, Clawgrip would be defeated.

Super Mario Advance
In Super Mario Advance, Clawgrip, instead of being a giant crab at the beginning of the battle against him, is simply a small Sidestepper. Clawgrip is grown to his giant size when he is engulfed by several bubbles which resemble the ones Wart is capable of spitting. Once at this size, Clawgrip, in a stereotypical pirate accent, will exclaim "Yar! You'll make a tasty treat!" and begin to throw boulders. After defeating him, he will say: "Yar! You got me" again in a pirate accent.

BS Super Mario USA
Clawgrip returns with the other bosses from Super Mario Bros. 2 in BS Super Mario USA. Like in the first game, Clawgrip serves as a mini-boss, and is fought in a similar way as in his battle from Super Mario Bros. 2.

The Super Mario Bros. Super Show!
Clawgrip made three appearances in The Super Mario Bros. Super Show!, where he, along with Mouser, Fryguy, and Tryclyde, was a minion of King Koopa instead of Wart. In all of his appearances on the show, Clawgrip wore a blue bandanna on his head.

Clawgrip's debut in The Super Mario Bros. Super Show! was in the episode "Rolling Down the River", where he manned the help of Captain Koopa's ship, the Sinister Star, while Koopa was making Mario walk the plank. The Mouth of the River used a cannon to fire a Turnip at Clawgrip, knocking him down onto the ship's lower deck.

In "Pirates of Koopa", Clawgrip can be seen among the minions of Blackbeard Koopa waiting for his return to Pirate's Port.

Clawgrip's last appearance on the show was in "Mario of the Deep"; here, a Clawgrip attacks Mario, Luigi, Princess Toadstool, Toad and their Mermushroom companion in a sunken ship. The quintet avoid the Clawgrip by jumping over him and going through a hatch that was too small for Clawgrip to pass through. The characters commented that this Clawgrip was simply a Clawgrip, implying that Clawgrips are a species.

Nintendo Comics System
In Nintendo Comics System, Clawgrip, instead of being a single character, was portrayed as a species, all of whom seemed to work for King Bowser Koopa. In The Fish That Should've Gotten Away, several Clawgrips appear among the monsters trying to defeat Mario. Mario manages to avoid these Clawgrips, all the while being annoyed by Stanley the Talking Fish.

Nintendo Adventure Books
Clawgrip and some of his GLOM-created clones try to attack Mario while he is exploring the Mushroom Kingdom in Double Trouble, but he manages to avoid them.

In Pipe Down!, Clawgrip appears guarding a tunnel which leads to Pipe World under the Mushroom Palace. If Mario and Luigi give Clawgrip a noisemaker or a pair of boots, he will let them pass peacefully, but if they give him a balloon (which he accidentally pops) or try to run past, he will grow angry and give chase to them. The brothers can distract Clawgrip by throwing some coins at him, but if they do not have any or decide not to give any up, Clawgrip will catch up to the two, leading to a Game Over.

Trivia

 * In the credits of Super Mario Bros. 2, as well as Super Mario All-Stars and the Japanese version of Super Mario Advance, Clawgrip is called "Clawglip." This is because the "r" sound in Japanese is closer to the "l" sound in other languages than by itself in most cases.
 * In Yume Kōjō: Doki Doki Panic, Clawgrip did not exist and his place as a boss was filled in by a third, albino Mouser. In the process of converting the Doki Doki Panic to Super Mario Bros. 2 for North American distribution, the programmers added Clawgrip, as this Mouser was perceived as too powerful. This makes Clawgrip the only Super Mario Bros. 2 enemy that actually was introduced in said game.Also Robirdo is another enemy that any appeared in Yume Kōjō: Doki Doki Panic.
