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, 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.
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).
