The title (and the text included) seduced me ! :P :P Gosh, I stink at picking corners. ;) 18 tries. There are 4 corners and I took 17 tries. O-O So cute ! (though it took me only 1 try). GREAT level ! Took me about 10 tries to get to a few off, about 15 to get to 2 off and 22 tries, all together. :) WOW! That's an excepetional level! Very tricky level. At first, I was going way around the butt to the pocket, as they say. :))) (41 tries) Very good level for the easy world. :) Ah hah! 7 tries. This would be a good fit in either the Easy or Medium world, I think. Nice simple level there for introducing locks and optimizing.
