The mystery is solved. Scooby, Shaggy, & Scout almost guessed it. They thought we were getting new carpet and we might have if the carpet didn't come clean.
We KNEW there was somefin up espeshully when we had to go in the basement and Mommy closed the door! But our food dishes we there and they had crunchies in dem. At least we didn't haf to starve. But then we kep hearing these noises, errrrr, eerrrrr, rrrrrrr and a big metal monster was outside. We culd see it from the winder. It was making noises too. Finally it gotted real quiet and the door opened. We went to run up the stairs and they were wet! And all our smells were gone! Now where do you fink our smells went?
Mom says she was mighty em-bare-assed acoz as you can see in the picshur the carpet was really dirty. The carpet man said our metal monster wif the hose wasn't doing the job in getting all our hairs out of the carpet. Plus it was dirty and making the carpet efun dirtier. Mom didn't want to em-bare-ass herself further an tell da man she hardly efur bacuums anyway. Now our job is to put our smells back where they belong.
