Sunny Holiday thinks that every month should have a kid-friendly holiday. Valentine's Day, July 4th, and Christmas definitely fit the bill--but months like January and August are lacking. So Sunny takes it upon herself to make new holidays for the months that need them, getting her friends and family involved. Sunny is headstrong, funny, and trying to make the best out of every situation--whether it involves holidays or family problems. She's got spirit to spare--and you can't help but love her for it.
