Stumpy primarily played a pup named Squiggy on Meerkat Manor, though he also briefly played as Izzy and Axel. His brother Ren played a pup named Len. In some versions of the show, he and his brother were called by their real names. Stumpy first appeared in On Dangerous Ground as Izzy and was seen being rescued from an owl by Sophie(Tina Sparkle). After Flower mated with Houdini(Aurinko) in the episode The Death of Romance, she gave birth to Squiggy and Len, but both did not make an appearence until the next episode, The Tale of Len/Ren and Squiggy/Stumpy. Both pups were separated from their mother in a group split. Rocket Dog and Mitch(Zarathustra and Pozzo) took charge of the splinter group. The pups were taken care of by Daisy(Finn), Sparkle(Bananas), and Mitch but sadly, due to a lack of food, the group struggled to protect the pair. Len was predated by a hawk, and Squiggy was later left behind by the group. Footage of Stumpy being abandoned was then used to briefly portray Axel in the episode Journey's End.
