Outside the clubhouse a large crowd has gathered around a hot air balloon with whisperings that someone is going on an adventure! Its Phileas Frog and Flea, they are about to start their expedition around the world in a hot air balloon. They set sail and wave their goodbyes to the crowd, when suddenly. Flea forgets Pippin, their potted plant! Roly runs through the crowd to save the day. But how will the squirrels look after the plant? Don't worry, Duggee has his Looking After badge. He can show them how to care for Pippin.
