Enemy #81 Fire Crawler not unlocked due to the game simply not spawning them into my game.

After doing some investigation in the game itself... its a glitch that either they give automatically to you when you enter Magma Chamber... or they don't give it to you at all and you get my situation. Loosing well over 15mins trying to figure out if i just didn't see them at the end.

Otherwise timing stopped at 5:17 due to me forgetting to talk to the old man to complete his side-quest.
