It's Kate's birthday and everyone in the habitat has something amazing planned- but Melman's worried that his homemade/hoof-made gift won't measure up.

Gloria becomes determined to earn her Queen of Kindness Kidizen badge and welcomes some free-spirited rats who need a place to stay into the habitat.
