Something that I learned is that Hydrosaur does not instantly have IF's if it does a quick chomp from part of the ice. That makes shots much more precise, but very abusable, and faster if you can nail their precise windows 3 times in succession. The 2nd hit is far, far easier on the Original Release because of how differently the AI behaves between the two editions of the game.

This is also the first sub-42 seconds run of this stage!

MOD EDIT: Changed the submitted time to match the run, you put it a few ms higher.
