Emma Gilbert

Emma's far too practical to believe in mermaids -- until she becomes one. Emma loves the water, but once she has a fin, she's forced to put her competitive swimming career on hold. Emma is more sensible than Cleo and Rikki, but she can be a bit controlling; sometimes the other mermaids don't want to play by her rules.

Special power: Emma has the ability to freeze water with her mind, and as an overachiever, she's determined to make the most of it.
Typical quote: "We've got to keep this a secret -- from everyone."
