This weapon has a built-in switch which, if flipped, would make anyone in a certain radius very confused, hence its title. The confusion is also accompanied with "duhhh" noises and salivation from the mouth and tongue.
Its first appearance was in the episode "Mermaid Man and Barnacle Boy III." At the beginning of the episode, SpongeBob accidentally gets confused from touching the switch, but he is stopped. Later, SpongeBob and Patrick attempt to use the orb of confusion to stop Man Ray from wreaking havoc, only to use it on themselves when SpongeBob flips the switch.
The Orb of Confusion was briefly shown in the Truth or Square video game at level "Meeting MMM and BB!!!"
In the video game The Yellow Avenger, Mermaid Man gives SpongeBob a mission to destroy the Orb of Confusion by melting it in the powerful toxic waste at the Industrial Park.
