It's a red-lipped fairy who's been living with the mermaids. The mermaids can't figure out what's wrong with her, but they can fix it. They can make her hair, make her lips coral, and make her dress a new one. The only problem is that she's missing her ring. She drops it into the gap between the bottom of the sea and the wall of the mermaid's house. The gap is too deep and narrow, so she'll never be able to get it back. Luckily, the gap is so small that she can fit in it. She'll have a party when she gets her ring back, and she can dance in the water just like she did when she was a little girl. The water is so crowded that it's hard to get in and out of the gap, but she can still dance and have fun.
