I always run but never walk often murmur but never talk have a bed but never sleep has a mouth but never eat.
I am full of holes but still holds water.
I store fire-breathing animals.
I can be hairy and itchy all over. I hang on a stick. I can be the scariest thing you have ever seen. I stand in the middle of nowhere.
