Ultimate Rescue: Pups Save the Pupmobiles - S7.E16

Sid Swashbuckle and his pirate pup Arrby steal all of the pups' vehicles (except for Chase's) to steal the Key to the City, which opens every door in Adventure Bay. Since Chase's vehicle was not stolen by Sid and Arrby, the pups work together in an Ultimate police rescue mission to recover the stolen items.
