The Squirrels are playing Copy the King when Tag falls over and bumps his knee - ouch. Duggee has his first aid badge, so he can bandage Tag up. The Squirrels want to help and they practise their bandaging on Tag. They do pretty well at first, but hang on a minute... where has Tag gone? And why is that huge bandage ball rolling down the hill? Hurry up Squirrels - time for a chase!

It's a day out! Duggee and the Squirrels are off on an underwater adventure with Betty's dad in his submarine. They see all the wonders of the underwater world, including a giant sea stallion and some jazz fish. And to the Squirrels, all those coloured buttons that work the submarine are just as interesting as what is outside. Betty's dad has a tricky time amusing the Squirrels. Thank goodness for the school of fish!
