Question: what do the symbols mean in gravity falls?
Answer: An open bag of ice: Represents someone who is cool in the face of danger, and Wendy Corduroy is the one to stand on the symbol in the finale, but it is stated that there is no specific carrier. A crescent/Pac-Man shaped symbol: Stan Pines - Stan's fez. A pine tree: Dipper Pines - Dipper's hat.
