The following day at a secluded beach, the six were about to jump into the ocean.

"Are you sure no one will see us here?" asked Quinn while looking around.

"Your father bought this beach just for this day, no one will be able to even get here thanks to all of the security unless they have the password and written permission from the family," said Rikki.

"Besides, once in the water we're faster than a torpedo," said Emma. All three moms then rushed into the waves.

"Whoa," said the girls as they watched their moms zoom out to sea.

"Well, what are we waiting for?" asked Jasmine as she took hold of Casey and Quinn's hands. They then jumped into the water and dove under the waves just like their mothers had.

"No way," thought Casey as she and the other two looked down at where their feet had been but were now replaced with a large golden tail each.

"This is so cool!" thought Quinn as she spun through the water. The three then noticed that Emma had come back.

"Looks like she wants us to follow her," thought Jasmine as she noticed the way Casey's mom was motioning to them. The four then took off for Mako Island. At the same time, Cleo and Rikki were waiting in the moon pool.

"Here they come," said Rikki as she noticed Emma and the others coming up from the tunnel.

"Alright, this is the coolest part of the day," said Jasmine while looking around at the cave.

"How can you like the cave more than the sea?" asked Cleo.

"Because I went scuba diving before and already saw it, but this is my first time seeing the moon pool you three were always talking about to us," said Jasmine.

"Well, you girls can go anywhere now that you have your powers but call to let us know first so we're not worried," said Emma.

"You also have to be careful not to let others know about this and watch out for full moons," said Cleo.

"Right," said the girls.

"Okay, I guess all that's left is to see just what you girls got," said Rikki before diving back down and racing out of the tunnel.

"Oh, you are so on," said Quinn before she followed after with the rest of the girls close behind.
