Kenner produced some pre-school playsets in the mid 1970s called 'Tots'. Tree Tots came in a variety of different playsets, such as the Tree House, Amusement Park, Lighthouse, Mountain Tots, etc.
The characters were small, measuring just a little over an inch. The first -and most popular- set was a large Kenner tree house. The canopy of the tree would pop open to reveal a home inside. There was an elevator in the trunk that you could put the Tree Tots People in at the bottom and bring them up to the top. A small tree or bush was home to the pet dog. There was a car, furniture, and family including mum, dad and two kids.
Although Kenner's Tree Tots developed a following, it was difficult to compete with Fisher Price, so the line went under in the late 1970s. Some of the molds were reused when Kenner produced the Ewok playsets in the mid 1980s.
