I love Koroks, especially the ever-tired ones that lop around with a backpack twice their size. They are charming and never... fail to make me smile whenever I come across them :)
There are two versions of this model: one is a hollow coin bank with a screw-lid bottom, and the other is a solid figurine. Both versions require all the supports they can get.
Please ensure that your slicer places enough supports under the feet, as they are small and completely floating. They will 100% fail if unsupported. So if the automatically generated supports appear too fragile, consider using manual/paint-on supports. Personally, I printed the ones in the pictures with organic/tree supports, and they worked really well on this model.
