Autumn Riddle

Autumn Riddle
Emily de Bono

I have a hard spiky shell, which is bendy and soft in the middle.

I am edible, but try to hide before the squirrels make me into a cake.

I’m smooth and brown and extra hard and strong. I come in pack of three.

Please spare me! Please spare me!

What am I?
(the answer is a beechnut)
