Pop is Olly’s friendly balloon sidekick. He doesn’t know too much about the world, but Olly helps him to make sense of it... Sometimes Pop even explains things to Olly.
He is a very happy balloon who not only likes to learn, but likes to be silly too!
His favourite colour is blue, but he also likes polka-dots. He likes to be outside but not when it is raining. Pop is usually full of hot air and his favourite animal is the cactus.
