How Do I Beat This Super Mario Maker 2 Level?

EDIT - Now with $30 reward and video of level below.

I cannot figure out how this is supposed to be done, can anyone tell me? I can get to the third room with a Boom-Boom guarding the key and the only way to defeat him I can see is 2 Bob-ombs in the top right but they explode before they fall down far enough to reach him. I don't understand, how am I supposed to do this? Thanks for helping!

Yes, I wouldn't be so persistent if I knew how to do it but I can't even figure it out.

There has to be a Developers Exit in there somewhere. Probably well hidden and hard to find now that they removed the edit feature from downloaded levels.

I keep suggesting this on Twitch whenever Aurateur does viewer levels but he hasn't played it yet.

I should offer a reward if anyone can even tell me how to get past the third room with the Rocky Wrenches.

I'm now offering $50 for anyone that can tell me how to defeat the Boom Boom under the AIM lettering. According to the online viewers, that Boom Boom contains a key needed to advance to the next room.

I don't know, but I see a red key at top left and a locked door at bottom right, behind bricks that can be cleared with one of the P-blocks. I have a feeling you can make progress if you get through that door before heading up to the area where Boom Boom is. I also note the ⇘ arrow right next to Boom Boom - maybe that's a hint to clear the uppermost coins on the lower level. 

The other thing I would try is go to that area and stand on the ground. Kill the Rocky Wrenches when they show up, but otherwise wait around and see if any Bob-Omb can fall down lower before exploding.
