The Shumulvault is the home base for the Hige-Hige Bandits in the anime Bomberman Jetters. This base is where Bagura keeps the unique items that are stolen by the bandits and was built by both Bagura and Mujoe.
In episode 40, Mechadoc unleashes his plot and takes over the Shumulvault. Later, the Jetters, along with Mujoe, invaded the Shumulvault to try and rescue Bagura. However, they failed. Mechadoc then warps the Shumulvault to a new place inside an artificial black hole.
It was once again invaded by Mujoe, and Bagura was rescued from Mechadoc, whom escaped the Shumulvault to Planet Jetters.
