I am the beginning of the end, and the end of time and space. I am essential to creation, and I surround every place. What am I?

I am dry when I go inside, but wet when I am pulled outside.
The longer I am inside, the stronger I get
When I am completely out, I am wet and I literally sag
Who am I?

I hide my treasure in the ground, my tail is big and fluffy. If you spot me in a tree, please don’t call me scruffy. What am I?

I look flat, but I am deep. Hidden realms I shelter. Lives I take, but the food I offer. At times I am beautiful. I can be calm, angry, and turbulent. I have no heart but offer pleasure as well as death. No man can own me, yet I encompass what all men must have. What am I?

A man calls his dog from the opposite side of a river. The dog crosses the river without a bridge or a boat and manages to not get wet. How is this possible?

I am the fastest animal but cannot climb the tree. What am I?

Two in a corner, one in a room, zero in a house, but one in a shelter. What is it?

I sleep during the day and fly at night, but I have no feathers to aid my flight. What am I?

What demands an answer, but asks no questions

You Throw The Outside, Cook The Inside
Eat The Outside, Throw The Inside.

What Is It?
