Blynk & Aazoo

Why do we have thumbs?

Our young inquirer, Rushi, asks our intrepid inventors, Blynk and Aazoo, "Why do we have thumbs?" With the help of our intergalactic science expert, Jessie, learn why humans have thumbs, which animals have opposable thumbs, and what extraordinary things humans can do without thumbs or arms. Blynk's invention, a backpack with multiple arms for cleaning, eating and drinking, glitches and things get out of hand.
