Octavio appears to be a large squid and wears a turtleneck, the uniform of his rebellion. He only walks with two legs, as shown in his animation.
Octavio appears to be bold, brave, calculative, and a little brash, seeing as how he rushed into rebellion on a misunderstanding.
Role in game
SpongeBob and Patrick arrive at the office to find Maurice and Jacques protesting. They join the movement and SpongeBob receives a uniform and the password to get past the lobster and see Octavio. He also gets in to see Dr. Louie and receive a stethoscope as a peace offering. SpongeBob then goes to find Octavio, with the latter not knowing that any of the previous events occurred in a cellar planning his rebellion.
SpongeBob comes into the cellar and Octavio trades words about the rebellion with him. When he mentions his anger toward Dr. Lumbar Louie, SpongeBob gives Octavio the stethoscope and the latter leaves to make peace.
