|—Frank, "Alternate Reality Show"|
Frank is generally quiet and collected. He has the stereotypical "cool guy" attitude, wearing sunglasses all the time and saying "sup" often. Being a contestant on Inanimate Insanity Infinity, Frank is very one-dimensional.
Frank is an upright hot dog, also known as frankfurters. He has a brown bun partially wrapped around a rusty red wiener. He wears a large pair of dark sunglasses.
- Frank, along with Hay Bale, were originally created as a contestant on Inanimate Insanity II but was eventually scrapped.
- His appearance was foreshadowed by Bow in Kick The Bucket when she said: "I'll be frank with you, Marsh, and I don't even know who Frank is."
- Frank's design is similar to Hot Dog Guy from the cartoon “The Amazing World of Gumball."
- Dave Zhu (Voice actor of Frank) did the storyboard for Alternate Reality Show. (And possibly in the future episodes)
