Sweetbi [Grass] -> Cherreen (Covered/Radiant) [Grass]
Cherreen’s form change is primarily based on the Pokemon’s health and mood/self-image. Cherreen that are unhealthy, eat poorly, depressed, think lowly of themselves, etc will be in their Covered form. Those that are healthy, eat well, are confident or arrogant, think positively of themselves, will be in their Radiant form. Whatever condition is the strongest will be the determining factor, so a narcissistic Cherreen with a ‘meh’ diet might usually be in its Radiant form, while a happy Cherreen eating nothing but Doritos and Mountain Dew might usually be in its Covered form. Like many plant Pokemon, their mood often changes due to the weather and sunlight.
