Does anyone know of a reliable way to affect whether these guys can throw high or low? It always seems to troll me every time in 3-4, costing me several minutes in the run.

?

I just know there's a certain factor that determines how they throw their projectiles upon entering a room. I just don't know what determines that, as high projectile arcs always cost me five or so minutes every run.

If you keep holding down through the first transition in 3-4 the eggplants never hit you.
