Urlusa or Morgana which sister is the worst?

I just purchased this movie the other day for our oldest daughters.

At the beginning of the movie you see Ariel and Eric going to see her father to show them the new baby (Melody). Ariel's father gives Melody a locket that shows her his castle and the mermaids. But then Ursula's sister Morgana come to try and take Melody away for revenge for the death of her sister Ursula. Ariel and Eric get her back and Morgana warns them that she will get her revenge. So Ariel decides that the sea is not safe for Melody and values that see will never know the truth about the mermaids and her family.

Melody (Ariel and Eric's daughter) has always love the sea and can't figure out while her parents don't want her to go near it. She slips out of the castle to go swimming and finds a locket that has her name on it. She asks her mother about the locket and she gets mad at Melody for going swimming in the sea. Melody runs out of the house and right for the sea. She gets a boat and meets some of Morgana friends. They take her to Morgana so she can "tell" Melody about the locket.

Morgana tells Melody that her mother is really a mermaid. Melody asks her to help her to become a mermaid and then tells her that she will not be able to stay a mermaid because some one has stolen her Trident. So Melody goes to out to find it. A long the way she meets two new friends. Ariel and her father reunite to save Melody with the help of her old friends, Sebastian and Flounder.

I will let you rent or buy to find out what happens next.

I couldn't that my 19 month old could just set and watch the whole thing without getting up. Its a great family movie and you will have good laugh at the same time.
