Prickly Pack
This was the sequel to Cactus Cube.
This is an entirely new puzzle, but with the same goal - Pack the box with the 3D pieces and then “plant” your cactus.
With this new design, the puzzle became a full blown Sequential Discovery puzzle. More than 10 steps until you are able to plant your cactus, with multiple tools.
A couple years later I decided to make a version of the puzzle without the packing portion, but instead made it a coin release - that puzzle is called Penny Pager.
