It was a certain day at the Mystery Shack and Grunkle Stan called out to the twins and said to them,"Kids! Pack and your bags and get ready for a trip!" Mabel asked,"Grunkle Stan, where are we going?" Grunkle Stan then replied," We are going on a plane trip to Central America and you're gonna be able to see different wonders over there." Dipper was really curious and wanted to know about Central America so he decided to purchase a book about Central America and a book of Mayan legends and mysteries. The next day, Grunkle Stan and the kids were packing their bags and got their luggages ready for the morning. It was 5:00 in the morning and the twins had to get their bags ready to put in the car.
