Arthur's 20th season kicks off on October 10th with four all-new episodes. The new season of Arthur will give fans a glimpse into the pasts, presents, and futures of their favorite characters.

In the first episode, Buster uses a comic book to travel back in time, but ends up changing his fate and friendship with Arthur. Buster also stars in a fun and topical episode entitled “Cereal”—a nod to the popular “Serial” podcast series—in which he seeks to uncover the truth behind a mysterious theft.
