Catch a Petilil in Pinwheel Forest (After 2nd Gym Leader) then trade it
with a girl in one of the houses in Nacrene City.
Cottonee's evolved form is Whimsicott. You get it with a sun stone.
At level 36 Oshawott will evolve into it's last evolvution. Unless the player stops the pokemon from evolving by pressing the b button, the pokemon will then try to evolve again every level it gains.
The Pokemon exclusive to the Black version are: Weedle Kakuna Beedrill Murkrow Houndour Houndoom Shroomish Breloom Plusle Volbeat Hounchrow Cottonee Whimsicott Gothita Gothorita Gothitelle Vullaby Mandibuzz Tornadus Reshiram
The only way Petilil will evolve is when you give it a Sun Stone. This is also true on how Whimsicott evolves from Cottonee. So basically: Cottonee + Sun Stone = Whimsicott, Petilil + Sun Stone = Lilligant.
