I know the feeling. The developer swears that the bebs stop somewhere between 100 and 105 if you have 4200 but but you have to have the time build up to get them cleared off using the mega bonus's. I have been up to 4500 and over 125 moves a couple of times and they still come. I do know that if you don't stop the game you get the "count down to less bebs needed" but I have yet to get them to stop dropping so i don't know the trick to stopping them yet. Maybe its just a way to keep our interest until he launches the new game update. He swears theres a way so I figure theres only one and its a stumble on it win type thing. Good luck and let me know if you do it. I think you'll be the first.
