This glitch is fairly easy to do. (My friend tuaght me). It allows you to walk while fishing. oh and thank danniell not me. danniell is the account name of the person who taught me. thanks dan! Ok here are the steps:
1. Go to the very first dock on the very right (this glitch works only in Donald's Dock and at your house).
2. go to the very edge of that dock and face it from the side.
3. jump with one foot hittin the dock and the other hitting the water. also called a half jump. WALLA!!!!!
you can now walk while fishing.
Also there is another glitch where you can use 2 lines to catch to fish at once, but im not gonna spiol the fun. Figure it out yurselves

LOL!!!
