Risko

Anyone know how to catch a Sunflora I've been running around in the grass in Obsidia Park for a while now and haven't ran into one. Does it have to be Sunny? If so how do I make it sunny? Thanks for the help guys.

Please don't add Mega Evolutions Pokemon CO. ruined last game with that. I love how you made this game difficult, added the status effects to stay after battle, brought back the look of Gen 3. Loving it so far thank you!!
