Lambert the Lion

Lambert is a lion who serves as the main character of the cartoon short Lambert the Sheepish Lion. Stan Freberg provided Lambert's only line of dialogue while June Foray provided Lambert's purrs and growls.

Background
Lambert is the adopted son of Mrs. Sheep, having been accidentally brought to a meadow alongside some baby lambs. He is initially very cowardly until his adopted mother is put into danger, whereupon he displays amazing courage.

Story
Lambert is brought to a sheep meadow on accident by a stork. Upon seeing the baby lambs with their new mothers, he chooses Mrs. Sheep to be his mother, much to Mrs. Sheep's joy. The stork realizes his mistake almost immediately, and attempts to take Lambert to South Africa where he belongs, but is stopped via a headbutt from Mrs. Sheep.

Lambert attempts to play with the other lambs, but is teased for his decidedly un-sheeplike appearance and habits. This culminates in a headbutting contest which Lambert loses badly, leading to his cowardly habits.

By fall, Lambert has become a fully-grown lion, but still remains the butt of the jokes of the now-grown sheep. This changes one night, when a wolf attacks the flock. When the wolf threatens Mrs. Sheep, Lambert is petrified and assumes the flock will help, but they run and hide. Hearing his mother cry for help, Lambert snaps and becomes a raging lion, roaring at the wolf and headbutting the wolf off the cliff he stands on. Due to his courage, Lambert is held in high regard by the sheep who had previously teased him.
