The animation and sound effects are a good reflection of the video game. In one episode (“Toddler Terrors of Time Travel”), the son of King Bowser invents a time machine to go back in time and stop Mario, Luigi and Toad from ever coming to their kingdom. The heroes stow away, and everyone ends up as toddlers in Brooklyn.

Video game character Sonic and his sidekick Tails repeatedly foil the evil Dr. Robotnik, including a four-part quest to the past where Robotnik seeks the four all-powerful chaos emeralds in the times of Blackbeard, King Arfur, Sonic’s ancestors and prehistory.
