Dark Cloud 2 Glitch - Out of Bounds From Angel/Devil Coins
A glitch with Angel/Devil coins that pushes you out of bounds while playing as a monster, preferably the Skeleton Soldier or Baron Balloon since they can go through walls a little easier, or the Ridepod. This requires the coin to be as close to an invisible wall as you can possibly get it, which rarely happens. I was able to get this glitch to work in nearly every dungeon. The only dungeon I couldn't get this to work at is Moon Flower Palace, even after reloading the dungeon hundreds of times.
Since this glitch works in every other dungeon, it's now possible to visit every star path without ever using the star key, but since this glitch rarely happens, doing that would take so long that it's not worth it.
I also show some unused fishing spots that can only be accessed while out of bounds, these spots can be found at the middle and star path floors of Starlight Canyon and Barga's Valley. These are the fish that can be caught at these locations:
Starlight Canyon Middle Section - Umadakara (Only when raining), Gobbler, Nonky, Gummy
Star Path & Barga's Valley - Gobbler, Nonky, Gummy, Heela
