Chumpkins is a Tabby cat that made his first appearance in Fallout New Vegas Mods: KDS Portable Camp Stuff - Part 1 and Fallout New Vegas Mods: KDS Portable Camp Stuff - Part 2 Al made it his goal to let Chumpkins survive the entire mod by protecting him, but Chumpkins didn't even make it till the end of the first part due to Al dragging him into a frag mine, causing him to die and setting off the 4 fusion bombs in his body, which caused Al to die as well. Chumpkins later returned in part 2 of the KDS portable camp stuff, but Chumpkins died once again, this time being killed by a Super Mutant carrying an Incinerator, which caused Al to die again.
Chumpkins appears again in Fallout New Vegas: Identity Crisis 2 - Part 5  where we find out Chumpkins barks (like a dog) instead of meowing like a cat. Al quickly comes to the assumption that Chumpkins had eaten a dog. Later in that same part, Chumpkins gets hit by a frag grenade (thrown by a Fiend) and detonates once again killing everyone, sending them flying across Spring Mt. in a rather humorous way. This is shown at 18:39. Chumpkins also makes an apperance in New Vegas Montages: The Return of Jerry McGhoulBerry where Chumpkins explodes, killing Voci after he stepped on Chumpkins.
He recently appeared in the Christmas special where Al sent him to kill the man who was making laser guns and supplying them to the fiends. Later he was seen in The Return of Janet being dropped from a bomber onto the Business Radroaches' bunker.
Chumpkins makes another appearance in Al's "Happy Fourth of July" video. In the video, he is put in control of the fireworks and when he is told to detonate them, he ends up blowing up half of Goodsprings with the fireworks. Chumpkins was spawned via a Chumpkins Grenade during Fallout New Vegas: Wasteland Defense - School Time - Part 2. He was teamed up with Jerry to attack Super Mutants attacking from the rear while Al and Cuddles defended the front and Janet and Steve guarded the children. Shortly after Al ran away, Chumpkins exploded; killing all of the enemies and knocking Jerry unconcious.
