The Hot Dog Duffel Bag is a bag that first appeared in the short "Unboxing". Its first full-length episode appearance was "Same Old World" and has also appeared in "Mr. Greg","Legs From Here to Homeworld" and "Familiar ". Steven showcases it as the highlight of his unboxing video.
The Hot Dog Duffel Bag is a large duffel bag shaped in the form of a hot dog. It has a beige bun with mustard and ketchup toppings, with two handles attached to the sides.
According to Steven, an estimate of the bag's length is six-and-a-half hot dogs long (or 7 metric bratwursts).
Its material is stain-proof, as shown when the Slinker's goo fell on it and it was easily cleanable.
