The Happos Family
When the last car races out of the safari park and the gates are shut to all visitors, the Happos jump up out of the mud, wake up from their snoozing and get dressed up. Now it's their time for crazy, zany, Happo adventures.

Fixit builds a tree house for all the Happos to enjoy, but Captain and Napoleon have taken it over and won't let anyone else in. Fixit and the Happos have to be creative with rope, a ladder, a see-saw and sausages to get them down.
