This is a remix of @Levin_Studer_1239141's frog model. I've added a hidden compartment in the front belly of the frog which can be held closed with small 10mm magnets.

I also developed the artistic plan for this frog from @Coilbuilder_88933 design of a Pickerel Frog (https://www.printables.com/model/863344-pickerel-frog). I recreated his colors and design within PrusaSlicer for my model. Whether or not mine is an accurate color representation, I don't know. But it seems to look pretty good.

The pictures of the frog are immediately after removal of supports, so I could have done quite a bit more to refine the finish through sanding and maybe an epoxy coating. The drawer required some light sanding on the top and bottom edges, but then was a smooth snug fit. I don't even think the magnets were necessary in the end.

Printed with the following settings: layer height 0.2mm, 3 perimeters, 15% infill, Organic supports everywhere, support top/bottom z-contact 0.2 (detachable)

Filaments used were all Matte PLA from Duramec3D: Olive Green, White, Chocolate Brown, Beige, Black

I had to make some changes to the drawer after I had completed the main body painting in PrusaSlicer. I didn't know if I'd be able to transfer the paint settings to a new model, so the main frog body was left referencing "FrogBox v8.step", while the drawer references “FrogBox v10.step”. There are no changes to the main frog body between the versions. I'm also enclosing the Fusion 360 file in case anyone wants to modify it further. 

If you don't have a multi-color printer, you could always just print the model as single colors and then paint yourself.
