"Last BFDI" is a video created as a celebration for 20,000 subscribers. It shows a vertically scrolling animation of a Rube Goldberg machine containing all 31 contestants of BFDI and BFDIA combined (but no hosts), creating and destroying them over and over. The song in the video is based on "Last Step" by Dubmood who was a member of Razor1911.

|Fries||Fries come from Donut; container comes from one of Blocky's parts||
Fries turn Nickel into Coiny; container is crushed into nothing
Note: Fries and container are separate in both the commencement and the termination. They're temporarily put together in between.
