Cerberus Retired — Goldeen Ogawa

All Professor Odd wanted was show her friends a marvel of engineering: a train built to run through outer space between planets! Then the train is hijacked by pirates, and it's up to her and Elo and Alister and Dave to save the day. But the marauders have a sinister connection to Professor Odd which could prove disastrous -- especially for her friend and protegé, Alister Bane. “Cerberus Retired” is the finale of Season 2 and the twelfth episode in the otherworldly adventures of Professor Odd and company: Elo the mutant wolf, Alister the misplaced university student, and Dave, the mysterious green tentacle creature.
