Duggee is cleaning the clubhouse so the Squirrels take refuge in the treehouse, but it's getting a little bit cramped these days. Norrie has an idea - maybe they need to add an extension, just like her dad does when she gets new siblings.

Duggee has made a beautiful rock pool, a place of calm for all the animals. The Squirrels spot the strangest things - dots with tails, wriggling around. What on earth are they? They are baby frogs - tadpoles! But they don't sound or look like Frog.
