Ultimate HP potion: talk to far right guy in the bar (upper right building). Get the transmute spell, find/buy some blue jungle berries, transmute them, bring it back to the guy, play another round, when you come back you will get the Ultimate HP Potion! It gives 892 health and +26 HP Regen fro however many battles. Unfortunately you can only get it once.
the loader's broken - usually if I close the tab and reopen later on the game loads instantly, but this one goes through the same (slow) loading % every time.

I went with Vaeonex's mix, but couldn't get the combo because I was too slow. Tried swapping out longer worm with shorter worm and jagged spikes with sleek spikes, got 122 combo before mega vacuum.
So, to recap: bigger wings ("bonus for playing on kongregate"), shorter worm, sleek spikes, blood fangs, flame jets, shredder teeth (and then mega vacuum if you don't get it w/ shredder teeth)
