Seriouser Kidnapping

Seriouser Kidnapping was planned to be the 40th episode of Space Tree, but was eventually discarded. Instead, the episode The Potato Farm was released in its place. 
The episode's name was added to the episode menu of the Space Tree website right after the release of The Clerman Clones - Episode 4, until it was replaced by The Potato Farm. 
According to a post on the Space Tree forum by Ed Atlin, some of the storyline planned for this episode went on to be used in Serious Tingling.
