Dr. Mu’s latest hair-brained plan is to invade the Earth using pizza. Harvesting the cheese mountains, giant tomatoes and olive groves of Princess Gelina’s homeworld, Dr. Mu has built up the biggest pizza chain in the multiverse. And with his profits he is constructing a giant, pizza-shaped starship called the Death Pizza. Can Rufus escape the clutches of Dr. Mu’s pizza-troopers, rescue the princess, destroy the Death Pizza and save the Earth? Well, maybe, but only if he can remember the ingredients of a Four Seasons.
