Name: Dancing Fool
Description: You got the fever and danced 100 times.
Simply dance 100 times. Whether you die or not, every time you hit RT, you will get one added to the dance counter. I suggest the first level in World 2 that teaches you how to dance, there is a long distance at the beginning that allows you to basically get in 10 dances until you hit the object. Just die, do it 10 more times (depending how fast you hit RT, you could significantly decrease the time) and achievement unlocked!
