I have eight legs. I spin a web.

Who I am?

I live in the house. I eat everything.

I am small and grey. Cats eats me.

Who I am?

I am the king of the jungle. I like to hunt.

I sleep 18-20 hours a day. 

Who I am?

I live in Africa. I am Yellow and Brown.

I eat leaves. I have a long neck.

Who I am?

I am a desert animal. I am tall.

People like to ride on me.
