The fight between Luffy and Crocodile starts from episode 122
In Episode 110-120 I think. During the Arabasta scenario.
Luffy's bounty went up to 100,000,000 (100 million) beli from 30,000,000 (30 million) beli when he defeated Crocodile.
It depends on which version you watch. In the 4kids tv dub, Luffy chases Crocodile down into some ancient ruins and then beats him up because he sweats, which is water, thus allowing Luffy to beat up Crocodile. In the Raw version, its the same scenario, except it is because Luffy is bleeding so much.
Genzo gave Luffy CPR in episode 39 and 40 also Nojiko resumed CPR on Luffy in episode 40.
