Gnomeo & Juliet
Benny is a member of the Blue Gnomes who are led by Lady Bluebury and live in Miss Montague's garden in Stratford-Upon-Avon and feud with Lord Redbrick and the Red Gnomes, who live next door in Mr. Capulet's garden. He is best friends with Lady Bluebury's son Gnomeo and aids him in a lawnmower race against a Red Gnome named Tybalt, who cheats to win the race, much to Benny and Gnomeo's annoyance.
That night, Benny and Gnomeo sneak into Mr. Capulet's garden to get revenge on Tybalt by spraypainting his lawnmower. After spraypainting a well in the garden, Benny accidentlly triggers a security light, causing both Blue Gnomes to flee.
Benny later sees Gnomeo with Lord Redbrick's daughter Juliet (whom Gnomeo is in a secret relationship with) and runs off when they notice him. He runs into Tybalt, who chases after him on his lawnmover whilst wielding a trowel and chops the top of Benny's hat with it. Gnomeo then arrives and fights Tybalt, who smashes after coliding with a wall. Benny and the other Blue Gnomes are saddened when they believe that Gnomeo was ran over and killed by a truck (where in fact it was a blue teapot that fell from the truck).
Wanting to avenge Gnomeo, Benny goes onto Miss Montague's computer and orders a powerful lawnmover called the Terrafirminator. Upon getting the Terrafirminator, Benny drives it, but it goes out of control and destroys both gardens and gets stuck, resulting in a battle between the two groups. An alive and well Gnomeo arrives and goes to help Juliet (who had been glue to her pedestal by Lord Redbrick as not to lose her like her late mother), but the Terrafirminator crashes into them, causing the other to think that they are dead. Devestated that their feud caused this, the Blue and Red Gnomes make peace just as Gnomeo and Juliet emerge from the rubble alive.
After the Blue and Red Gnomes union and Gnomeo and Juliet's wedding, Benny finds the long lost wife of a plastic flamingo named Featherstone.
