Defend Your Planet!

An idea for a Henson produced game show called Defend Your Planet! (also cited as "Attention Earthlings: Defend Your Planet!") was mentioned a few times by Henson officials. The concept was human contestants faced off against humorous puppet aliens to win in a battle of wits and strengths to save Earth (and win prizes). The initial concept was worked on but it was never produced, however some rumor that a small test pilot was created at some point and is now buried in the Henson archives.
