Well. First talk to Fleuve in the lab to get modle OX.Then at his 2nd form, jump over the lazer balls and hit him, when he drops the rocks, go in between them and air-roll-slash(jump,hold down wile in arr and keep slashing) untill the 3ed form. Then watch out for the slowing spore and when hecrushes the rock, dash to a side and jump, then dash back to the middle to avoid the hands. Also, make shore that u have the wind boots chip equipped so you wont slide back. There, a full-proof plan to kill Serpent.

Huh?
