Eureka!! I found it!!

Yes, it is a good idea!! You have thought of a way to bring you and the other Megas Back together. You decide that you will dress up as Santa Claus, a fat old man who delivers presents to humans.
"If the humans get presents from him," you say aloud. "we Pok�mon should get presents from him, too!!"
You put on the Santa Hat. It is colored in a deeper shade of green that you are, and makes you look even cooler than before.
"But Santa doesn't only dress in a hat. Without a better costume, everyone will know it's me." you think aloud. Then you remember the store in Cherrygrove city. You think of going back there, but you are in too much trouble to be seen there again for a while. You think about the store in Goldenrod City. It is much bigger, and has a wider selection of items. You know that the chances of finding a green Santa Suit there are better than the chances of finding one in Cherrygrove. You walk along the path to Goldenrod City, but you find that it is blocked by a strange, deformed looking tree. What to do, what to do?
