He is friendly and welcoming towards R.J., and seems to be a well-meaning father.
Role in film
Initially, he and the other animals are scared when they discover that during their hibernation, there has been major development in their neighborhood, greatly reducing the amount of forestry, and they fear they will be unable to forage for food in the small glade. RJ shows them the amount of food humans consume and waste and suggests they forage from the humans. Verne is hesitant but the other animals acquiesce. They make bold attempts to steal food directly from the humans, with RJ secretly guiding them to help collect the food he needs to replace Vincent's stash.
When the animals raid the trash cans of the homeowners-association chairwoman Gladys Sharp, she calls an animal exterminator named Dwayne LaFontant, who offers to install an illegal, lethal trap called the "Depelter Turbo" in her backyard. Verne sees this and tries to warn the others, but RJ insists they will be okay.
After a brief argument, RJ and Verne make up and RJ rallies the others to raid Gladys' home directly on the night before a large party. With Stella disguised as a cat to distract Gladys' own cat, Tiger, the others enter Gladys' home and collect all the food. RJ inadvertently reveals his duplicity to the animals, just as they are discovered by Gladys who calls Dwayne. RJ escapes with the food for Vincent, but leaves the other animals to be captured by Dwayne.
However, RJ has a change of heart and goes back to help them, which results in him and the other animals breaking free, and Spike, Bucky and Quillo use skills they learned from a video game to drive the truck back to the development. RJ pleads to be let in the truck as Vincent tries to catch him, but the others, angry at his treachery, refuse. Verne convinces the group to forgive RJ since he came back to save them. They return the truck to the development, crashing through Gladys' home, and the animals flee into the hedge. Gladys and Dwayne converge on the animals from one side with a String trimmer and a Cattle prod respectively, while Vincent tries to swipe at them from the other. Ultimately, thanks to some quick thinking from RJ and Verne, and Hammy assisting them by aligning a variety of objects while moving at the speed of light, which he's able to do after finally being allowed to have an energy drink, all of them get caught in one of their own traps and are subsequently stung by the Depelter Turbo. Afterwards, Vincent is taken to the Rockys, while Gladys and the Verminator are arrested for using illegal traps. The rest of the animals then formally welcome RJ to stay with them as part of the family.
