Accepting that Peter might be happier as a wild animal, the Griffins reluctantly agree to let him live in the forest. As they say their emotional goodbyes, Meg steps up to bid him farewell.

He immediately regains his full human consciousness and returns home to his daily life. 📺 Crossovers and Notable Gags [S11E17] Bigfat
