Actually I thought that Goomy was a Mythical Pokemon, and it said Mythical Pokemon are being turned to stone. So I thought the Goomy was going to get turned to stone.
My friend corrected me, telling me that Mew, Celebi, Jirachi, Manaphy, Victini, and Diancie are the Mythical Pokemon, and Goomy is a Pseudo-Legend. I still really don't get why those six aren't counted as actual legendary Pokemon, since they have been for the first four generations...
