Performed by: Alyson Stoner (Olivia Flaversham) Later in the afternoon, Olivia Flaversham and Fievel Mousekewitz had put on their swimwear. And now, they were standing on top of a tall rock near the waterfall cave. Olivia was wearing a baby blue two-piece swimsuit and a matching hair-bow. Fievel was wearing red swimming trunks with blue lining. Fievel was the first to grab a rope and swung in the entrance to the cave as he shouted, "Tallyho!" And he plopped in the water. "Come on, Olivia." said Fievel, as they swam out of the water and onto the rocky land in the cave. "Me too, Olivia." Fievel said.
