Didn't work for me
I did this using Google Chrome. Don't worry about it if it doesn't work though. In my understanding, it's just another method of playing the game with the same result as if you had clicked the same frog repeatedly. I managed to grab the avatar after using this method, but I don't think those two events were necessarily related. Fairly positive this doesn't give you an advantage, but people are free to test it if they like.
