Numberblock Eight is known by his superhero name: Octoblock. He’s got eight arms (or are they legs?) and when he needs to run fast, swim a long way, climb up high, knit in a hurry or more he changes shape to activate a unique special power each time: Octoblock Run! 1-2-3-4-5-6-7-8 Run! The perfect T-shirt for all those little heroes.
