Mr. Jumpy Tower

The twins couldn't understand why I was a little miffed about their cool invention. I was upstairs paying bills and all of a sudden Soren is at my side, adamant about the fact that I need to come see "Mr. Jumpy Tower". What's a Mr. Jumpy Tower? The pictures below explain what I found. All the pillows from our couch and every blanket in the closet out and placed in a pile, perfect for jumping on. Good thing I don't give a darn about this couch! They had a great time!
