brer rabbit and the blackberry bush

Today, I read "Brer Rabbit and the Blackberry Bush", a series of Usborne First Reading, leveled 2 book.

Brer Rabbit and Brer Fox are always up to mischief. Now Brer Fox thinks he has the perfect plan to stop Brer Rabbit once and for all. 

I thought Brer Rabbit is so smart. Weak creatures have to use their brains for surviving.
