People who say this boss is too easy are people who mustn't have tried to do the full 20 hearts star on this level... sure, it's not a very hard boss, but it comes after a very long level and right after another boss fight. Hanging onto all of your health by that point is so hard...
I have no idea why, since I didn't know what an SNES was at the time, but when I saw this, I actually thought this was the final boss for the ORIGINAL Yoshi's Island... I was also like 5 or 6 at the time and I am 13 now, so...
