Question Mark Block Knock Shell Delivery in Super Mario Maker 2

Here we'll hit a question mark block, which will make an enemy pop off of it in a usable form for shell tech. It'll fall off in the direction in which it's closest, so to be more predictable you'll make 2 enemies (that don't walk off ledges) fall on the block forcing them to get stuck in one direction. One will usually be a shell, the other being an enemy that will die by the hit.
