Happy Birthday, Battle for BFDI!

Happy Birthday, Battle for BFDI! is a short video released to celebrate Battle for BFDI 's first anniversary. It was released on November 3, 2018.

Plot
The video starts with all the BFB contestants (except David) all in the anniversary wheel. Bottle says happy birthday to BFB. She is looking forward to more adventures with all her friends. She then says that their next adventure would be their most difficult one yet, but they're working hard and can't wait for the viewers to see it. She then says to enjoy this cake for now. However, Remote points out that the cake is made out of cardboard. Bottle then grabs Cake. Everybody eats Cake while he yells in pain.
