Then the pet kangaroo was heaved in through the doorway, and fell on its head and raised the dust.

A great many ugly dogs rushed for it savagely.
The kangaroo jumped up and bounded round the ring.

The dogs pursued him noisily.

"GERROUT!" Joe shouted, and the crowd stood up and became very enthusiastic.

The dogs caught the kangaroo, and were dragging him to earth when Dad rushed in and kicked them in twos to the top of the tent.
