It's the Easter Beagle, Charlie Brown!1974

Linus van Pelt:
Every Easter the Easter Beagle comes dancing along with his basket full of eggs, which he hands out to all the good little children.

Sally Brown:
That sounds faintly familiar. I remember sitting out in a stupid pumpkin patch all night waiting for The Great Pumpkin to come. And you know something ? He never came! That was the worst night of my life.

Linus van Pelt:
But this is different. That was Halloween. This is Easter.
