To complete my puzzle collection online I still had to make a picture of a solved Happy Cube (also known as Snafooz or Wirrel Warrel).
For some extra information to add I found the site Happy Cube with a new collection of Happy Cubes, solution and even software you can download which helps you to solve Happy Cube.
For me a new lovely puzzle experience with an old puzzle. You can buy Happy Cube / Snafooz at PuzzleMaster Inc.. Happy Puzzling!
