One of the things I get a lot of Email about here is the Kenner Tree Tots line, a fondly remembered pre school series that captured kids imaginations in the late 1970s.
I personally remember the line well, being eight years of age at the time, it was first time in my life I regretted being too old to play with something, that feeling plagues me to this day....:
The classic tree tots family tree house,
A tree roller coaster, that's kind of pushing it.
A tree house/Light house, brilliant extension of the concept.
A Mountain Hideway, apparently the Tree Tots family were enemies of James Bond.
