Monster Castle - S2.E39

After Jumpy Ghostface is zapped by Twin Masters, Jumpy's dreams start coming to life and Jumpy Ghostface's dreams are mostly about evil monsters (consisting of Moosey Ghostface and Tri-Puppy) and a dream version of Beastomp. Jumpy Ghostface banishes the dream monsters by dreaming up a giant version of himself and forcing them back to Woo the Wise's new invention that sends the monsters back to the dream world.
