The Planet of the Apes Treehouse wasn't based on anything in the films but was a repackaged version of Action Jackson's Jungle Treehouse but seeing as Caesar lived in a treehouse in the previous year's "Battle for the Planet of the Apes" it made perfect sense. The treehouse was an incredible seller for Mego, in an October 1974 Playthings magazine the Treehouse was listed as "outselling comparable toys 20 to 1".

Value: $500.
