It's the Pied Piper, Charlie Brown

It's the Pied Piper, Charlie Brown is the 39th and last animated special produced under the supervision of Charles M. Schulz.

Based on characters from the comic strip Peanuts, it was originally released exclusively in VHS and DVD formats on September 12, 2000, seven months after Schulz's death.

[1] Charlie Brown recounts the story of the Pied Piper of Hamelin to his sister Sally.

In this retelling, the town suffers from a mouse infestation, as Sally insists on substituting mice for rats, which she dislikes.

To address the issue, the mayor contracts the "Pied Piper Beagle," portrayed by Snoopy, promising him a year's supply of dog food as compensation.
