Revealing mistake: In the colour version of the battle with the Crazy 88, the Bride swings herself onto the restaurant's upper story balcony. When two of the Crazy attack her and she slashes the second one, toppling him off the balcony, he is spraying water, not blood.
Suggested correction: About a minute earlier in the fight (in the extended colourized version), about a half-dozen Crazy 88 members are knocked into a fountain and get totally soaked. He's one of them. If you look, you can tell his entire body is still almost dripping wet when the bride slices him. So he's not "spraying water instead of blood." Rather, the water that's already on his body is simply splashing outward as he whips around. (It's a little confusing because the black-and-white version omits the fountain shot and tries to "cheat" the water as blood since you can't tell it's not red. But in the extended colour version, it really is just the water that's soaked him that's "spraying" outwards.)
Yeah, a plausible explanation. Except that 1) when the Crazy is running onto the balcony, none of his clothes look like they're soaked. His jacket is fluttering as he moves; whereas, if it were wet, it would be hanging down. 2) His hair, when he strikes and The Bride parries just before she hits him, is showing no shimmering of wetness before he "sprays." 3) As much water as he sprays when hit, he should be dripping with water when he comes onto the balcony, which he isn't.
