A dance-a-thon is held by TNS West in the hopes of creating a scholarship fund so that dancers who cannot afford the expenses of dance will still be able to partake in the activity.
After learning that Heather is no longer able to dance because her parents cannot afford it, Piper proposes to Michelle that they hold a dance-a-thon so that dancers who cannot afford dance will still be able to do it. She organizes the event, for which willing participates must receive pledges to get money.
The dance-a-thon is a twelve-hour long event. The dancers are expected to dance for the 12 hours and receive additional money for each hour they dance (for example, if somebody received a pledge of $5, they would get $60 for dancing the whole 12 hours).
Piper has the most pledges, but is unable to dance due to a sprained ankle. Heather takes her place. Heather and Henry are the only ones who dance the full 12 hours and tie for first place.
