Wallace & Gromit: The Curse of the Were-Rabbit (2005)

Something wicked this way hops.

Cheese-loving eccentric Wallace and his cunning canine pal Gromit run a business ridding the town of garden pests. Using only humane methods, which turns their home into a halfway house for evicted vermin, the pair stumble upon a mystery involving a voracious vegetarian monster that threatens to ruin the annual veggie-growing contest.
