The exquisite corpse adventure

It all begins with a train rushing through the night. On board, twins Joe and Nancy begin a quest to rescue their parents. Along the way, they will encounter mad scientists, a talking pig, creatures from another dimension, several bad knock-knock jokes, plenty of explosions, a whole army of villains and varmints, and shape-shifting Eggy-Things. Figuring out who is friend and who is foe is the least of the twins’ problems as they piece together the body parts of a Top-Secret Robot who, when complete, will help to reunite their family.
