"II + BFDI back together again!" is an announcement video that was released on June 18, 2019. In the video, Michael Huang and Adam Katz announce the crossover between BFDI and Inanimate Insanity for a meetup on Sunday, July 14, 2019, at the With Love Market & Cafe in Los Angeles, California; the same place where they met up the last year.
- This video uses puppets instead of being animated.
- Despite a Four puppet appearing in the thumbnail, it doesn't appear in the actual video.
- The puppet style of the characters is a callback to the April Fools joke in "Bowling, Now with Explosions!" where viewers were made to believe that the episode would be using puppets instead of being animated.
- Cloudy calls Pen by his legal name, 🅱en, which was revealed previously in "Fortunate Ben".
- The plot of the first section of the video is a callback to "Don't Lose Your Marbles", where the contest was a red-ball collecting contest (Cloudy's Red Ball Collecting Club) and Pen finding an apple, which also happened in the same episode.
