What's that smell?!??!

Yesterday I smelt something bad in Erianna's room, but couldn't figure it out... Today I took down her huge tent and started looking around, but found nothing... The smell was getting really bad, and then tonight, we found the culprit. My husband took the kids fishing on Saturday. Erianna packed her bag complete with three dolls, sweater, chips, Twizzlers, pencils and paper. Tonight when beginning her homework, I asked her where her pencil box was, and she said she must have left it in her other book bag. Upon opening the bag, the smell was unbearable. Her loving brother had planted a shrimp at the bottom of the bag on Saturday, and two days later in warm South Florida you can only imagine the smell!!!
