Specter Stoppers

Once again, Baljeet asks Phineas and Ferb for help with a science project, this time with an interdimensional portal. When Phineas and Ferb test the portal they open a portal into a realm of the undead, and accidentally release an army of ghosts. Phineas and Ferb then create ghost fighting gear, and hunt for the ghosts along with Baljeet.
