Heres where to go: Donalds Dock. Here is what to do: Go on a dock and exit it when you go in the water swim back into the dock but before you go in it jump backwards in the dock.

The Effect: It will glitch up and down and allow you to walk ( or run ) with the pole in your hands. It will also allow you to swim go outside the area and cast still. The things you have to watch out for is running out of jelly beans or fishing time! Have fun!
