When the whole house goes to a fair, Mac and Bloo compete to see who will throw up last on a ride called the Vomit Comet. Bloo ditches Mac to ride in Madame Foster's Firebird, but a "quick" stop at the fabric store that is just across the street from the fair suddenly turns into a nightmare for Bloo that doesn't seem to end, causing him to take big measures to try to get out of it.
