In "Just One Bite," when Squidward is being taken to the hospital by an ambulance, Joe is seated next to Squidward's disembodied head, holding a bucket containing the rest of his body and legs as he recalls his first Krabby Patty
In "Funny Pants," he is seen with a fellow paramedic that looks identical to him at the Krusty Krab when they were eating lunch and laughing at SpongeBob's joke. Later, he was seen putting Squidward on an ambulance because he broke his laugh box.
In "The Smoking Peanut," Joe and an identical co-worker are seen trying to calm down Clamu at the Bikini Bottom Zoo. Clamu threw him into the air, but he survived. Joe was seen again at the end of the episode cheering in the background when Clamu had a baby.
