The city zoo bought a new kind of kangaroo (袋鼠) from Australia. It was for jumping very high. The zoo keeper was worried that the kangaroo would , so he built a 3-metre-high wall around its home.
, the next morning people found that the animal was playing around outside. So the zoo keeper made the height of the wall 5 meters. But the kangaroo again the following day. The zoo keeper felt very angry, so he made the wall as high as 10 meters, but the kangaroo still got out.
"How high do you think he'll keep on building the walls?" a monkey asked the kangaroo.
"I don't know," said the kangaroo. "Maybe it'll reach 300 meters if the zoo keeper still forgets to lock the gate."
