It's the time of year that Betty and her family take a family trip to a pirate-themed amusement park, leaving X-5 to take care of the house, but not before X-5 hands Betty his new invention. Meanwhile, in space, Greenbeard's ship has fallen apart whilst in the middle of stealing jewels from the planet Pacula./ Betty and her crew is with her uncle Charlie, where they are enjoying the Moose Jaw Heights Rodeo. Sparky is ecstatic, not because he has never been to a rodeo, but because of the prospects of food. When Charlie asks Betty and company if they want to ride a horse, Sparky insists on riding the untamable horse, Thunderbolt. Meanwhile, Dr. Cerebral has arrived at Crushton, intent on finding spare parts for his latest scheme to destroy Atomic Betty.
