Same here! I stick the hammer dude in the first bend and buy another 400 one for the middle...then I usually save up for a 200 one and stick it somewhere in the last bend and usually that gets me to the third level without letting any of the fans through...but after that it gets much tougher and I start losing alot of Mayor HP D:

I like the spinning green ones best...they have a lot of HP but they're slow, so I can usually wear them out before they reach the mansion xD But I hate the blue ones...soooo tough! Dx
