Rest Home Rangers (S02E43)

As the Rangers prepare a big birthday party for Monty, Professor Nimnul is downtown at the convention center attempting to go straight. He unveils his latest device, the "fast oldness generating instrument experimental ray" (Fogie), a gun that will instantly age milk into cheddar cheese. During his presentation the gun runs out of prunes, its power source, which causes Nimnul to go into a rage. He raids a nearby grocery store for more prunes and gets most of the place with his recharged gun, including Monty who was there for some cheese. Nimnul then heads for a prune factory for endless supply of the dried fruit to power the Fogie. (iTunes)
