The Tickle Belt is one of Mermaid Man and Barnacle Boy's many ingenious gadgets. It is used to keep Man Ray from performing crime by tickling him. In the Mermaid Man and Barnacle Boy original series, the Tickle Belt was put on Man Ray by Mermaid Man in the #17th episode.
The Tickle Belt appears for the first time in "Mermaid Man and Barnacle Boy III." A remote and key come with it. The tickle belt is attached to Man Ray's waist, and a button, LAUGHING TIME is pressed to make him laugh like crazy until another button, STOP, is pressed. The tickle belt also has music that comes from the key hole in the middle. It all sounds like laughter and happiness to go with the moment. The Tickle Belt foiled Man Ray's plans of robbing a bank because the effects of the tickle belt caused Man Ray to keep laughing even though it had been removed beforehand by SpongeBob. Oddly, the tickle belt reappears in subsequent episodes featuring Man Ray even though it had seemingly disappeared in "Mermaid Man and Barnacle Boy III."
The Tickle Belt is a pure blue color. In the center is a key hole which can be unlocked by its key that comes with it as another way to stop the tickling.
It spins quickly when tickling. (feathers and sparks appear later in the episode) They only appear if the belt has been damaged, so the belt will tickle more.
The music that plays when the Tickle Belt is on is "Hahahoho - The Big Laugh" by Jürgen Schlachter. This song is available from the APM music library, where many of the show's songs are found.
