In Rabbid Mollusk a rabbid wears it like it's his hair. The Octopus then teases him but very soon begins to attack the other rabbids, who pull it's tentacles and send it flyng to Louie's window,who kicks it. At the end of the episode the octopus falls onto the window of the Fugitive's car and causes both of them to crash. However they survived and the octopus had landed on Mona (Louie's wife)'s face.

In Kite Rabbids the rabbids use it to play with the fan, who is not very happy about this but is rather angry.

He appears in Rabbid Elevation where a rabbid used it once again as his hair. And is seen floating when the elevator starts falling very fast at the end it and the rabbids see a light and think it's the moon, but only for them to see that they just crashed.

It is seen again in N°98004 the animals where it is one of the test subjects and Jessica want him to win since he was the most intelligent of them all. It manages to do all the tests right exept the last one where the rabbid tries to hit a fly with chicken eggs. But he just kept stopping the octopus from reaching the donut and, at the end the rabbid even throws an egg in it's face. The scientists then open trapdoors to all animals and they fall down.

In Rabbid Rules of order,he tries to go to the bathroom but the lifeguard rabbid doesn't let him,but he managed to go anyway,at the end the rabbid kicked him in the ocean, his ferocius Mother then forced the rabbid to serve him.
