Third boss of the game is one of those who were shown in the early trailers, yup, he's that giant crab in the first OoE trailer. Well, not much to say, he's actually easy to beat but hard to perfect. First tower, once you get to a dead end, just duck down on the leftmost bottom platform and start spamming him until he turns red, when he turns red, just remain and let him punch the ceiling for two times, then if you'd sacrifice a hit, then just stay or if you don't want to, after the second punch, immediately run into the center and do two backdashes and he should punch the center and you'll avoid getting hit, since the third punch will surely hit you if you stay on the bottom left platform. So after he destroys the ceiling, rush to the next dead end and he should do the same attacks he did before, turn him red again but this time you can choose to just duck down on the upper left platform and let him punch it three times for you to continue. Next, like before, rush to the dead end and stay on the upper platform first, once he settles down, go down the bottom left platform and spam him w/ attacks, well, he has one additional attack here, after he uses the bubble attack, go to the upper platform to avoid his pincer slam, well, you'll avoid it if you stay but you'll get hit by the small arm so you'd need to just to the platform above for safety. Turn him red, and like before, duck down on the leftmost upper platform and let him destroy the ceiling, once destroyed, magnes your way up until you see the elevator, jump on the space available and get on the elevator and press down, poof, the stupid crab's dead.
