The Quest of the Easter Trail

'Ere you venture out the door
  be sure you go behind or 'fore
Your sister must be the other
  to find what isn't by your Mother.

Here's a little roll that sends you
  up, around, or in a tree.
Which one it is,
  you'll have to see.

For your next clue if you please,
  you must get down on your knees.
If you crawl 'neath the desk of Christoph,
  On the back the clue you'll liftoff.

Now to an instrument you must go.
  One that's large for quite a show.
If among the strings you look,
  you'll find a clue inside a book.

Now to where you bounce you'll head,
  but under there you'll go instead.
If you go right to the middle,
  you'll find the next clue of the riddle.

It's time to head to the front door,
  and to the outside at the floor.
If you look there under the mat,
  that is where the next clue's at.

This clue is going to make you think.
  If you were washing at the sink,
what you would need when you were through
  is where the next clue waits for you.

Up and up and up you go
  to the highest floor that you know.
Find what you use the clothes to pin,
  and you will find a clue therein.

At the house's lowest point,
  near three concrete faces joint,
there's a drain for water flow.
  It's to that grate you must go.

For your next step (if you dare)
  you must look for silverware.
Then look near the ice cream spoon.
  On this clue you'll find a moon.

All together you now must go
  to where the clothes get warm.
Fold them all and you'll uncover
  what you are wanted to discover!

To finally culminate the quest
  you must pass this final test.
You must be three, one's your sister,
  the other is the families mister.

What does he have in his pocketses??
