Mr.Peabody and Sherman make teleportation suits, but when the battery runs low, they end up into the Orcopti-Tron, causing it to go into short circuit mode! Now, it's up to Maria Garcia to host the show.
Peabody and Sherman went to the year, 386 AD to visit Mulan, to stop the Huns from taking over the kingdom with assistance from Christine, who stumbled onto the machine. However, Mulan may not need Mr. Peabody and Sherman's help after all.
