S1, E9: Thanks to the well-intentioned bumbling of Mrs. Brown (Pamela Britton), the trash collector picks up Martin's spaceship for scrap. This sends Martin (Ray Walton) and Tim (Bill Bixby) on a desperate search for the missing vehicle, which is Martin's only possible means of transportation back to his own planet. With the help of an eyewitness--a dog!--our two heroes trace the ship to an amusement park, where it has been converted into a most exotic carousel.
