In his first appearance (Episode 3852), he was just named Sparkles. Elizabeth lost him, and Telly Monster and Baby Bear found him, and named him Little Murray. When they realized that he belonged to Elizabeth, they returned him and explained that they called him Little Murray because he looked like one. Elizabeth agreed and decided to call him "Little Murray Sparkles."
While his owner Elizabeth disappeared after Season 32, Little Murray Sparkles continued to make named appearances through Season 36. He was seen in the company of Telly Monster in the Elmo's World segments "Bath Time" and "Cats." He also appeared as the "ferocious" jungle cat in episode 4139's "The Adventures of Gina the Veterinarian," and as an audience member in The Not-Too-Late Show with Elmo. An identical Muppet cat has appeared on Shara'a Simsim.
