I fondly recalled the plastic “snake” that was popular during the “Rubic’s Cube” era, and adapted it into critter tails. Designed in wood with retro-but-current art, these guys are hard to put down! This is one of my all-time favorite toy designs-simple, durable, cute. At left you can see the first concept sketch, and on the right, the cleaner 2nd sketches. You can see that they changed a bit yet again in the real product- that happens a lot!
