Duggee is a lovable brown dog who runs The Squirrel Club; a place where children take part in all sorts of exciting activities and earn badges for their accomplishments! Duggee is blowing up balloons for Tino the artistic mouse's birthday. The squirrels are a little worried because Tino can be a bit grumpy! But Duggee persuades them all to go and see Tino and give him a bunch of balloons. When you give a tiny mouse a big bunch of balloons, something unexpected happens. Tino starts to float up into the sky! He's having a rather good time until he gets stuck in a tree. It's time for the squirrels to come to his rescue.
