Rosie doesn't want to host a Sleepover but won't tell the others why not. When they devise a plan to go into her room, they find out why! On a secret mission to refurnish her room, they call upon the assistance of her father, David, and her brother, Will. The M&M's loose a bet with the Sleepover Club and have to serve them smoothies at the Beach Hut Café dressed in bikinis. Presented by Fliss.
