Blocky's Funny Doings International (BFDI) is a series of Blocky pulling pranks on other contestants. Blocky's Funny Doings International currently has 10 different pranks, with 4 of them in BFDI, 3 in BFB, and 3 non-canon ones that only appear in Blocky Prank Compilation - Battle for Dream Island or jacknjellify's TikTok.
The first four pranks demonstrated in this set of ads revolve around rigging recovery centers to recover and immediately cause the death of a character. This then creates an infinite loop of recovery and a death of said character. The fifth prank involved giving the enemy team a cardboard spaceship that would burn up if it's close to the sun. The prank was unsuccessful, and caused the Have Cots to have an advantage in the following episode. The sixth and seventh pranks involved committing perjury to waste everyone's time, causing Blocky's Funny Doings International to be on hiatus for 2,763 years.
