Patchy the Pirate (who is portrayed and voiced by Tom Kenny) was created as a multimedia host who would most notably appear in various commercials and bumpers, acting as a "bridge" between the actual episodes and the tie-in promotions. Because of this, most of his appearances are outside of the show's episodes. He still makes occasional appearances in the live-action segments of specials, but the vast majority of his screen time is in on-air promotional materials. When viewers only look at Patchy's in-episode appearances, they miss almost all of his actual backstory.
This page lists Patchy's appearances in any media throughout the seasons, including promos, marathons, bumpers, and episodes themselves. Please note that this list is incomplete because footage of many older Nickelodeon events is rare.
Since there are no special episodes in season one, Patchy does not appear in the season itself. Instead, he hosts this special feature on The Complete 1st Season DVD (2003). When the player selects an object, Patchy appears in person to talk about it.
The original airing of "Shanghaied" was a special event called "You Wish" where viewers called Patchy to request one of three possible endings: SpongeBob's, Patrick's, or Squidward's. In footage that was cut from all later airings, Patchy answered the phone and appeared in an ending scene where Potty wishes he turned into a puppet.
For the 2004 Kids' Choice Awards, Patchy appeared in many bumper appearances. In one, he then talks on the phone and gets interviewed at the exact same time, and eventually does his best to multitask.
He hosted this alphabet-themed marathon that led up to the premiere of "Atlantis SquarePantis." In the marathon, Patchy wore a diving suit in the middle of a giant fish tank. He also worked as a lifeguard.
Original airing only: Patchy finds a book of legends that he reads to Potty as a bedtime story. In the rerun version, Patchy's book and desk are still seen and shown at the beginning.
Minor appearance; He works at Christmas Land Theme Park dressed as Santa Claus, and then gives SpongeBob, Patrick, and Plankton a map to the North Pole. He later appears in a picture that SpongeBob gives to Plankton in the Krusty Krab on Christmas.
