Thank you, PawPaw and GrandMissy!

 Thank you for our wonderful marble run.

 

  I was excited when it came and followed the diagram to set up a very neat run,

 but I soon realized that I needed to set my marble run standards a little lower for the time being...

 H enjoyed examining the different blocks and helping me stack them into a slightly more simple track.

(C liked to tap the blocks together)

 It has a neat xylophone staircase that makes a little music when the marbles hit it.

 It was fun to find all of the places for marbles to go

Thank you!  I can't wait to show it to you!
