What am I?

Riddle 1
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.


Riddle 2
No legs have I to dance,
No lungs have I to breathe,
No life have I to live or die
And yet I do all three.

Riddle 3
You walk into the forest and get me,
You sit down to look for me but can't find me,
You get up and leave with me.

Riddle 4
Only one colour, but not one size,
Stuck at the bottom, yet easily flies,
Present in sun, but not in rain,
Doing no harm, and feeling no pain.

Riddle 5
Weight in my belly,
Trees on my back,
Nails in my ribs,
Feet I do lack.
