This is just a dumb joke. Baby Yoda with the Rock's head stuck on top. 

A remix of https://www.thingiverse.com/thing:4644812 and https://www.thingiverse.com/thing:4772809/files. I found the Rock model somewhere online.

There are pins to connect the hands to the body so I've included those files too. There are pins included to connect the body to the head of the original model but those aren't needed anymore because I've made the body and the Rock's head one piece. I used Blender to mix the two models.

For the model with its arm out, that can be printed on its own without any of the other files.
