Click that green thing that makes things work (the green flag not the red stop sign) and watch. When you've watched all the different hippos remix this and add your own! You also have to add your username to where it says; say ( ) for 5 secs. Go ahead and add a comment underneath your username but don't make it look like it's part of your username. Remember it's Your Flying Hippo. Be creative! But don't do anything outside the base of the hippo.
Thanks to bouncycookie for the original!!!!
