Tata, a Squirrel Monkey Jewelpet, is leaving town one night due to his disappointment at not getting his own Magic Gem. He then stars at the Red Moon and gets mad, but the moon attacked him with countless rocks. Kosuke tells Ruby to use her magic once more, which increases her size as Kosuke ejects from his plane and Ruby lands on the ground. With the only way to stop Tata is through size, Ruby must take him down before it is too late.
