Willy Weasel

Willy Weasel (Possessed by Jerry Robert Willis) is the titular main antagonist of the 2021 horror triller film Willy's Wonderland. He was once a friendly animatronic and mascot at Willy's Wonderland, but after being possessed by serial killer Jerry Robert Willis (who had performed a satanic ritual to transfer his soul into the robot), he became a murderous robot bent on killing and eating everybody in his sight .

History
During a majority of the film, Willy does nothing more than stand on stage, sing, and summon his friends to attack the Janitor, with most of his evil actions being shown in flashbacks. However, after all of his animatronic companions are killed, with the exception of Siren Sara and Tito Turtle, Willy became angry with the Janitor, and killed Eloise Lund when she tried to summon him on the latter. Willy throws the Janitor into a wall, causing confetti to shower and a distorted version of the birthday song to play. Willy slashing at the Janitor multiple times with his claws before throwing him into the ball pit. Believing he has killed the Janitor, Willy walks off, unaware that the Janitor was still alive. Furious, the Janitor makes makeshift weapons, taping the two broken peices of the broom he broke earlier while fighting Ozzie Ostrich, and filling a sack with cans of Punch Pop soda, to fight the weasel. During the final battle, Willy gets the short end of the stick, recieving several blows from the Janitor. Willy is then knocked to the floor, where his hesd is brutally bashed in by the Janitor, mortally wounding him. As a final move, the Janitor rips of Willy's head, finally ending his reign of terror and avenging the lives of several innocent people who were killed.
