Gerald is a sea lion that appears in the 2016 Disney/Pixar film Finding Dory. A running gag is when he comes up on Fluke and Rudder's rock, both of them bark, "Off! Off! Off!" at him. Fluke and Rudder mistreat Gerald and steal his green pail. Ultimately, however, he manages to sneak onto their rock as they sleep.
The cruel treatment of the other sea lions toward Gerald drew controversy and criticism from many audiences, as it appeared that Gerald had an intellectual disability of some sort and his bullying was played for laughs. Pixar denied this however, saying that Gerald was a caricature of a "playground nerd" who is victorious in the end.
