Can you find the missing piece of the Porsche?

John’s parents have three sons: Snap, Crackle, and what’s the name of the third son?

I can sizzle like bacon,
I am made with an egg,
I have plenty of backbone, but lack a good leg,
I peel layers like onions, but still remain whole,
I can be long, like a flagpole, yet fit in a hole.

I live in a bowl. I can swim. I have a tail. I also have fins and big eyes. What am I?

It comprises roots which nobody sees,
Much taller than those trees,
Up and up it goes,
Still it never grows?

The more you take me, the more you leave me behind.
Who Am I?

What is the riddle which can be asked all day with a different correct answer each time.

Lifeless eyes on my smiling face and watch your child's sleeping place. In their dreams they hold me tight. 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?

What jumps when it walks and sits when it stands?
