When it comes to water Pokemon, I have a lot of favorites because water is my favorite type. My number one would definitely have to be Kyogre. Other close favorites are Buizel, Floatzel, Totodile, Crocinaw [sp? too lazy to look up], Feraligatr, Mudkip, Marshtomp, Swampert, Piplup, Prinplup, Empoleon, Vaporeon, Mantyke, Mantine, Maril, and Azumaril.
Yeah, that's almost all of them for ya. Yay for blue and orangies. X3
