A BFDI is the prize of Battle for BFDI, it is unclear what it is supposed to represent, or even what it does, but the contestants seem to be excited that it is the prize.
It is a deep-fried image of the BFDIA intro with one-third of the Bandicam watermark (only saying www.Bam) above it, as well as a non-deep-fried segment of the BFDI intro (from the video "BFDI: The Complete First Season" by walshmjoey's) with the underlined word "Official" on it.
- There is an official "a BFDI" acrylic block for sale on RedBubble, which can be found and purchased here.
- There is also a pillow, a pair of pants, and a skirt with the same design.
- The BFDI logo is taken from an unofficial video compiling all Season 1 episodes of BFDI, because it shares the same length of 3:38:23 (the video was taken down due to a copyright claim by jacknjellify).
