Unstable Fables: 3 Pigs & a Baby (2008) on Netflix

Plot summary

A team of wolves has already failed once to capture the three pigs. Their next attempt is to leave a wolf cub at the pigs' door and let the household take him in. The pigs raise the cub as their own and call him Lucky, and he becomes the newest member of the household. He grows from a baby into a teenager in their home. The wolves are a special-ops unit, and the cub at the pigs' door is how they mean to get inside the house. Lucky knows nothing about the family he came from, or about the role the wolves have in mind for him.
