[No.] 24A [Episode Name] TED and the Beanstalk [Air Date] April 17, 2006 [Description] 
When Jim and TED are collecting lunar seeds for Eco, TED loses his balance while carrying a heavy seed. So he trips over Jim, and Jim, TED, and Rover all fall into a deep ravine. They're unable to get out because it's too steep to climb up and all the vehicles are too big to get into the ravine and rescue them.
