This is Cema Tree.

Cema Tree can grow up to six feet tall. It is edible but it tastes yucky. Only stupid people or famish people will eat it. However it is very useful as building material. Two Cema Tree trunks can make a coffee table.

On top of the Cema Tree trunk, there is a large round ball of grass, and around the grass ball, there are a lot of thorns which are useful to make needles. Be careful while picking them or walking by the Cema trees, and I warn you to not sit under it in case some thorns fell down and might hurt you.

After you pick all the thorns, you can use the ball of grass as a toy. Or if you are a very good knitter, you can use it as a yarn ball to make a sweater.
