It's Halloween at the farm and Zee and MacBarm are excited to tell the tale of Jack O'Lantern on a haunted hayride. When the Zee Mobile gets stuck, the Mechas need to find a way to get it down so it can pull the hay cart and save Halloween./Timmy can't wait to go trick-or-treating as a Mecha T-Rex this year, but he's having trouble holding his treats in his costume. The Mechas work to make a pulley that will let him use his dino arms to collect treats all night long.
