And, would you believe it,
The very next week
Leo, the lion
Just happens to get
Hopelessly tangled in
Game hunters' net.
Mouse happens along,
Says, 'I'm small, with no roar,
But there's one thing I can do,
And that is to gnaw.'
In less than an hour
The net's nibbled through…

Do someone a goodturn,
He might do one for you.
