[No.] 4A [Episode Name] Up, Up, and Away (almost) [Air Date] January 5, 2006 [Description] 
When Jim and his friends explore inside a cave, TED offers to guard outside. Bored, he decides to try driving Jim's Lunar Crawler. But he accidentally moves a large boulder which blocks Jim's entrance to the cave. So Jim tries to exit from above the cave using his gravity boots, but the boot controls are broken and he's about to float into space. So it's up to TED to learn how to drive the vehicle in order to bring Jim back down.
