I have only girls, but they love these:
Bite Me from NG (smells like fruit punch, but it's speedy for me. I hate to soap it, but I have too because the kids love it so much)
Snow Fairy from Bert's (divine! smells like blueberry and mint.)
Liquid Crack from Daystar
Cotton Candy from NG (it's supposed to be non-discoloring. I've only HP'd it. It doesn't discolor in HP, but when it gets wet, it tends to discolor an bit. strange.)
Huckleberry Harvest from NG (grape and berries sort of)
High Voltage from SGS (I've heard that is is the same as Energy from BB)
Monkey Farts from NG (this one was a bit speedy for me, but it was one of the first I soaped and have not soaped again. it could have been my fault because of the newbie factor)
