Pete Puma debuted in the November 15, 1952 Rabbit's Kin, a Merrie Melodies short directed by Robert McKimson, from a story by Tedd Pierce. Animation was by Charles McKimson, Herman Cohen, Rod Scribner, and Phil De Lara. He is voiced by Stan Freberg.
Though Pete Puma made only two appearances, in Rabbit's Kin and in Pullet Surprise, he is often vividly remembered by cartoon fans, especially for his bizarre, inhaled, almost choking laugh, called "ihhhhh" (based on comedian Frank Fontaine's "Crazy Guggenheim" character). In Rabbit's Kin, Pete is chasing a young rabbit (named Buster Rabbit by some fans; and though he is called Buster at least once, in the cartoon Bugs repeatedly calls him 'Shorty'), who asks Bugs Bunny for help. Bugs is eager to oblige, and subjects Pete to some of his trademark pranks.
More recently, he has made occasional appearances on Tiny Toon Adventures (as the Acme Looniversity janitor), episodes of The Sylvester and Tweety Mysteries, co-starred with Foghorn Leghorn in Pullet Surprise (voiced again by Freberg in all of these appearances), made a cameo appearance in the crowd scenes of Space Jam, Carrotblanca (as a waiter), Tweety's High-Flying Adventure, Bah, Humduck! A Looney Tunes Christmas (in which he is once again a janitor), and is a supporting character in the Looney Tunes comic books.
Pete appears in The Looney Tunes Show episode "Reunion" voiced by John Kassir. He is shown to be a friend of Daffy Duck and Marvin the Martian. He also appears in "Devil Dog", as a zookeeper. Then in "To Bowl or Not to Bowl" as Daffy's teammates. Also in "Sunday Night Slice" where he works at Speedy's pizza restaurant, which was called Giradi's, and once again in "Working Duck" where he was watching the cart of EnormoCorp's muffin man.
