After finding an old bunker in the middle of the woods, Dipper, Mable, Wendy, and Soos find a man who claims to be the author of the Journals of Gravity Falls. Dipper and Wendy soon find out that the man isn't what he claims to be, and is actually the true author's old experiment gone rouge and trying to break free of the bunker: The Shapeshifter. Dipper and Wendy hold off, and soon they prevail and Mabel and Soos trap it in a freezing trap. So now you can be the Shapeshifter in Minecraft! I hope you enjoy!
