The Sloppy Jalopy is Oscar's junk car in Follow That Bird. Since his horn is broken, Oscar has a Honker in the backseat to fill that function. A ragged umbrella covers the back area, and a "Big Bird or Bust!" sign is hand painted in a ragged scrawl. The license plate reads, "SCRAM."
This car is also featured in the 1997 video Fiesta!, where it was being used as a carosa (float) by the kids to replace Rosita's broken float. Elmo thought that a fairy godmother transformed his pineapple into this Sloppy Jalopy as the float for the kids.
In the 2009 storybook, Love, Elmo, Oscar is fixing up the Sloppy Jalopy to use it as a taxicab. The car has a sign painted on the side: "Oscar's Taxi Service: Ride At Your Own Risk".
