Bender is shocked to see Cubert and Dwight playing Dungeons & Dragons. After crashing the Planet Express ship in a game of bumper cars, Fry, Leela, and the Professor encounter Mom and her three sons. Suddenly, the ground splits open, and everyone falls into a fantasy world. After climbing out of the hole, Leela transforms into a centaur, Bender appears as a knight riding a giant horse, the Professor becomes a wizard, Amy becomes the queen of the water nymphs, and Zoidberg turns into a giant squid (with just a head and a few tentacles). Soon after, orcs mounted on kangaroos launch an assault, scaling the city walls with ladders. Knight Bender, Wizard Professor, and Queen Amy are tasked with defending the city. Mom and her sons transform into dragons, fighting fiercely over the dice (a dodecahedron).
