Sky raft

Image your just soaring through the air with your elytra. As your flying over a pillager outpost your all of sudden shot by an arrow and begin to fall. The last thing you see is a raft suspended by balloons. I like to call this structure a sky raft. Sky rafts spawn above pillager outpost and have balloons suspending them. The designs for the balloons themselves include two fences stacked on top of each other, with a block of red concrete on top. Pillagers will usually spawn on these rafts guarding a chest that has valuables in it. Successfully killing the pillagers or knocking them off the raft, will award you with about 10 emerald max, a stone axe, and a couple wheat and bread. What if you destroy the balloons? If yoi destroy all the ballons keeping the raft suspended then the entire structure will disappear with the explosion particle effect accompanying it since I'm not going to expect Mojang to code physics. Any ways that's the entire structure
