"Shake It Up, Chicago!" is holding a dance marathon to raise money for charity and Rocky is quick to sign up to support the local senior center. CeCe, on the other hand, isn't thrilled with the idea of helping unappreciative senior citizens like Mrs. Locassio (played by Renee Taylor), but quickly jumps on board when she finds out the winners will also get a spotlight dance on the show. In order to prepare for the marathon, CeCe purchases some energy drinks to give them more pep in their step, but when Flynn gets a hold of the sugary concoctions, the girls are up all night with him and have to muster up the energy to compete the next day.
