The Sunflora Festival (Japanese: キマワリコンテスト Kimawari Contest) is an annual festival and competition held in Bloomingvale. It appeared in the anime in Grin to Win!. The competition is a beauty pageant for Sunflora, and the healthiest and happiest Sunflora, ranked by three judges, wins their Trainer a trophy and a year's supply of instant noodles. The people of Bloomingvale seem to find winning quite important, and have been known to use different methods, some enigmatic (e.g., taking one's Sunflora to a tanning salon or hiring a comedian) to enhance his or her Sunflora's smile.
