This weapon has a built-in switch that, if flipped, will make anyone in a certain radius very confused, hence its title. The confusion is also accompanied with "duh" noises and salivation from the mouth and tongue.
Role in series
"Mermaid Man and Barnacle Boy III"
At the beginning of the episode, SpongeBob accidentally gets confused from touching the switch, but he is stopped by Mermaid Man who warns him that prolonged exposure to the Orb of Confusion would give him permanent confusion.
Later, Man Ray turns it off and reveals his redemption prior to leaving. However, even though SpongeBob returned to normal, Patrick continued to be confused (this confirmed Mermaid Man's warning to SpongeBob from earlier).
Mermaid Man gives SpongeBob a mission to destroy the Orb of Confusion by melting it in the powerful toxic waste at the Industrial Park.
It briefly appears in the level "Meeting MMM and BB!!!"
