Go Sector 2-06 in Octo Canyon. At the entrance immediately after spawning, shoot the wooden box in front of you. Cover the ground and the platform below with ink, then swim through the ink and jump over to the bottom platform. Shoot the box on the right bottom area on that platform to get a food ticket. After collecting the food ticket, go to the menu, and return to Inkopolis Square. Repeat this process as many times as desired. You can only hold 99 tickets at a time. Use the tickets to buy unlimited Crusty Seanwiches from Crusty Sean, which boosts your experience earned in online battles by 50%. Note: This glitch was performed on an unpatched version of the game. It will probably eventually get patched. To avoid not being able to use this exploit, either do not install new patches before using this exploit or delete the patches. You can avoid patches being installed by disconnecting from the internet until you are ready for the game to install new patches.
