MoFU are transforming toys that are also brainteaser puzzles. Starting as identically shaped cuboids that slide out of boxes on drawers, each MoFU unfolds into a different kind of animal - pig, monkey, tiger, hippo, and giraffe. Each animal is its own character with cute and iconic features, but each is also a distinct puzzle. Folding a MoFU back into the correct cuboid shape so it can perfectly fit back into its box is a brainteasing challenge.
