Ending / spoiler
Directed by: Ron Howard
Starring: Tom Hanks, Eugene Levy, John Candy, Daryl Hannah
The government finds out that Madison is a mermaid, and she is hauled off to live in a lab tank for studies. Her boyfriend Allen and his brother Freddie (both human), disguise themselves as scientists and sneak Madison out of the lab. Madison and Allen then go to the ocean, thinking about either releasing her back to her ocean life or staying human and living with him, but they must make a fast decision because they are surrounded by the people who captured Madison. Allen then jumps into the ocean with Madison, and they swim around down there together, choosing to stay together forever.

Answer: The sea hag gives Madison a set of instructions she has to carry out, and tells her that she can only survive out of the ocean for six days. She also tells her she has to wet her tail every day, which is why Madison is seen in the bathtub.
