This is my version of the Minecraft Creeper. I actually made two: one with articulated legs and another with wheels (like most of my designs). It's very easy to print — you just need to attach the head using the built-in connector.

STL and 3MF files for multicolor printing. No suppots needed. You just need to attach the head using the built-in connector. Make sure you have good adhesion to the print bed, if necessary use an additive, in my case I use a bit of strong hold hairspray.
