Event
The Shooting Star Line was one of 15 Exclusive Pokémon lines to be added in the New Years 2015 event. Not being very different in the process of evolution of the Cleffa line in the original games, it is basically based on shooting stars and has something similar to Jirachi's tags on its body.
