Trivia[]

Twenty-Four[]
| “ | Okay, Zero. This has been a long game. You've won the most money EVER in this show's history! | ” |
— Twenty-Four, Thanks for 2,763,000 Subscribers!
|
Twenty-Four (24) is an Integer that appeared in "Thanks for 2,763,000 Subscribers!" They are the host of a gameshow, with one of the rounds being a spelling bee. They are voiced by Benjamin Cross.
Appearance[]
Twenty-Four appears as a hot pink colored number 24 with slightly different pink limbs. They sport a little black tie on the bottom right corner of the two part of their body.
Trivia[]
- Twenty-Four's voice references Host Bug, likely due to both being game show hosts and sharing the same voice actor.
- Them being a game show host may be because both Two and Four are hosts of BFDI, since they are a 2 and 4.
- Twenty-Four is most likely named Twenty-Four because in Insectophobe's Nightmare 2 (BFDI 24,) Goiky gets taken over by bugs, and Twenty-Four's voice actor is the same one as Host Bug. This is probably coincidental though.

- Although there was a recommended character called "Nonagon Polygon" in BFDIA, this was not the actual Nonagon and was instead a reference to the Animatic Battle character of the same name.
