A fully grown Cuddles with his top hat.
Mister Cuddlesworth (originally called Deathclaw Hatchling) first appeared in the video Fallout New Vegas Mods: Fourfer! - Part 2 , in which Al reviewed four mods in one series of videos. One of these mods was the Baby Deathclaw Commander, in which the player character would get a Deathclaw egg which would eventually hatch as a tiny baby, but would grow as it gets fed every hour and fought enemies, eventually becoming full-sized.
Al grew an attachment to the lovable Deathclaw, and so the Deathclaw has appeared in nearly every video Al has made since, making him the second most prominent character in Al's videos, next to Al himself. In the Chryslus Corvega mod review Cuddlesworth was given a top hat by Al (top hat is a mod and does not come with the Baby Deathclaw Commander mod). Subsequently, during the Willow Companion mod review, Cuddles gained the ability to turn invisible for a brief amount of time after he had found and eaten a stealth boy.
Mister Cuddlesworth, along with the rest of Al's main companions, makes his last official montage appearance in New Vegas Montages: Farewell New Vegas. He is first seen alongside Al as the group heads out for a Chicken Finger Fiesta at the Atomic Wrangler. The gang soon realizes that they are trapped in the establishment, with explosive bombs ready to go off any minute. Even though he is unable to find an exit, he escapes with everyone else when Ballarms shoots lasers into the floor, allowing them to fall into the sewers. Once in the sewers, an Al clone appears and begins decimating the civilians in the area, forcing Al and his gang to take cover while they figure out an attack plan. As they ultimately have no weapons, they run for the surface, where they wind up right in the middle of a Business Radroach attack on Freeside.
Al decides to take Steve and Jerry with him into the Strip to counter a vertibird approaching and tells the rest of his gang to hold the line, leaving Cuddlesworth behind for the time being. It was revealed that the group left behind was captured, although they were soon rescued alongside a captive Jerry and Steve and escape the bunker base, deciding to head for their base in Goodsprings. When they arrive in Goodsprings, a bomb is dropped, decimating the town and increasing the radiation to extreme levels. Because of this, Al sends Jerry, Steve, and Cuddlesworth into the radiation to try and reach their secret bunker, telling them that if they don't come back, he loves them. The trio ventures into the radiation-filled environment, finding Al's hideout among a pile of rubble
Before they have a chance to enter the base, clones of Al appear and soon overtake the group, moving on to attack Al once the trio is subdued. He, alongside the other captured companions, appear at the end of montage, having been brainwashed by the Radios and working for Crier Breach.
He follows Crier Breach as his mind-controlled companion until New Vegas Mods: Harry Mason Companion - Silent Hill!, where he and Captain Ballarms are rescued by Resistance Fighters.
