What Am I poem

Guess Who

I'm hard to break

I'm very small

I'm oval shapped

and also rough

I'm made from wood

I'm under trees

I come from trees necks

and up their trunks

you sometimes find me on the ground

sometimes wet sometimes dry

and if you were an ant it would be deep to dig

I'm sometimes loose and sometimes not

Kids always use me almost everyday

What Am I?
