It's a hot day and Duggee is watering the plants. The Squirrels help and after a while everything is wet and slippery. Roly slides along the grass, but hang on - that's not grass! Roly is sliding on a really long snake! Gerbie the snake is on holiday and would like to see all the beautiful sights. Duggee can help - he does have his tour guide badge!

The Squirrels are playing outside. Roly is digging in the garden when his spade suddenly hits something. It's a key. But what does it do? Duggee has his key badge and says they can find out through trial and error. The Squirrels go on an adventure to work out what the key opens and what could be inside.
