He later tried to catch a chicken and was tricked by Foghorn Leghorn. A regular gag involved him and Bugs Bunny having tea. Bugs would ask him how many "lumps" (of sugar) he wanted, and then would pound him on the head with a mallet until he got lumps. While Pete never appeared in many classic-era shorts, his goofball facial expressions and exaggerated voice always made him a fan favorite.
One of his first modern appearances was as the janitor at Acme Looniversity in Tiny Toon Adventures. After he took a fall from his own soap and mop down a flight of stairs, Babs and Buster Bunny (no relation) observed that he would now have "A Whoooole Lotta Lumps".
He later appears in The Looney Tunes Show as a zookeeper, not a very good one at that. He is given strict orders that if he values his life he will not open the lock for a caged wild animal. He then immediately rips of the lock and runs towards the zookeeper telling him he forgot his lock, leaving the Tasmanian Devil to escape.
