Rex the Runt S02 E13 Hole in the Garden

The Gang discover a prototype hover mower whilst clearing out Bob's shed. The major design fault is obvious when it burrows into the ground, creating a tunnel that leads all the way from the back garden to Australia. A shouting match with some dingos follows, at the end of which an enraged Bob accidentally throws Vince down the hole, precipitating an adventure of global proportions.
