Basically, you just go to the 'Kiss the Mortog' game and double click on the first frog. You should get an error page saying you refreshed too quickly. Press 'back' on the browser, double click the frog, press back, double click the frog. After 3-4 times, go back and click the frog once.
You will skip to the furthest level you would have achieved if you had continuously clicked the same frog. It may skip to level 2,3,4 or further depending on how many clicks were made. NP will be consumed for each click. This is a sort of timesaver method, but I don't think it will actually increase your chances of getting to the avatar. I tried this and got the avatar on the third try, but I'm fairly sure it was just luck and not a result of using this glitch.
