More General Remarks. Kanga never takes her eye off Baby Roo, except when he’s safely buttoned up in her pocket.
Therefore. If we are to capture Baby Roo, we must get a Long Start, because Kanga runs faster than any of Us, even Me. ( See 1.)
A Thought. If Roo had jumped out of Kanga’s pocket and Piglet had jumped in, Kanga wouldn’t know the difference, because Piglet is a Very Small Animal.
Like Roo.
But Kanga would have to be looking the other way first, so as not to see Piglet jumping in.
