Velma and Hot Dog Water (who was just released from prison) are discovered to be working for Mr E. and are going on missions for him; here they go to Russia to retrieve a piece of the Planaspheric Disc from an old house, but when they are stopped by the nightmare witch Baba Yaga they buy it and bring it to Crystal Cove where the house springs chicken legs and rampages over town. Meanwhile, the gang are looking to replace Daphne and Velma suggests Hot Dog Water.
