I like to design biomes for my minifigures. For example, the Orc and Rocking Horse girl from a recent CMF series share a build. The Orc, having come through a portal to the little girl's room, is playing on the rocking horse. Meanwhile, the little girl has taken the orc's cloak, sword, and shield to head through the portal.

I'm now working on what might be my most ambitious MOC. I have 3 minifigures that I realized represent seasons: Watermelon Guy (summer), Turkey Guy (Fall), and Snowman (Winter). If I get a Spring, I have all 4 seasons.

My first thought was to build 4 similar MOCs that would vary due to the seasons. It turned out that this would be too costly, though.

That's when I came up with a better idea. Each figure would be standing near a big tree. Each side would represent a season and you'd be able to rotate the tree to see the different seasons.

One problem: How do you build a MOC that can rotate? I don't need it to automatically rotate or use gears or anything. Just plain "push on the MOC to rotate it" works.

Any ideas?
