I heard that you can get a special Jellicent in the water of a certain town on a certain day. If you answer, please give me all details.
P.S. I have Black 2
From Serebii ----> This Jellicent returns to Undella Bay on Mondays in Black 2 and Thursdays in White 2. It has its Hidden Ability and is male on Black 2 and female on White 2. Thats about all you need :D
