The five mermaid princess swim out of 'terrible nightmare' song from shil and tila's power in the idol form voices. They have arrived at the under sea castle where the whales tales hide out ready to get there friends back. The morphed to their new idol voices not splitting up this time as they blasted front gate and doors down.

"get out of our way!"shouts shelly.

"move it or loose it!"yelled mizu.

"we need to get by you !"coral was trying to be nice.

"more out of our way!"shinju was ticked.

"you have a brain use it and move it!"umi was pissed.

All the girls got was 'terrible nightmare' song from shil and tila's power one after another dodging left and right .so shinju and umi in pearl idol form got together and them with their 'rising wave' pitch voice. This was a new offense attack that took the power to the green and yellow pearl voices as one. shil and tila wer blown into the air 10 ft before they came crush down in the ground of the sea bed. They couldn't believe the girls could combine there power like that as shil and tila coughed up dirt.

So the girl still in the undersea castle and done sending two of the obstacles away with one of their new attacks. Go on further in the castle looking for the glass pillar's that held their friends where they last were.

"this way."shinju points to a corner.

"round the corner all!"umi looked at each one of them.

"here we come guys!"coral pressed her microphone to her chest.

"ready save the day."cheered mizu.

"i hope their alright?"shelly was worried.

In the storage room of the under sea castle...

"they already took down shil and tila."whinto stood there thinking.

"i know that sir."a women spoke.

"hello mila!"he waved to her.

"their coming oh so closer to this room"she giggled.

"how will the whale rule over mankind with these dumb mermaid princess not on our side."he knocked his head on a wall.

"those dumb humans killing us for their own joy."mila snorts.

"i know with the power of the seven seas the whale once more will rule the ocean ."he laughed all evilly like.

"i know!"mila agreed with him.

Then the girl heard laughing coming form ahead them meaning they were getting near the room their friends were being held. They stopped in front a huge teal and golden door that was blocking their way. The girl got in a group holding their microphones up to their lips closing their eyes and did 'rainbow burst' pitch shine voice.

"WHAT WAS THAT?!"yells whinto.

"US!"the five mermaid princess entered through the door.

"MILA!"he ordered her.

"bad viel!"she shoots her attack at them.

They all dodged at once going all kinds of way through out the room as coral and mizu launched their 'friendship bonds' pitch voice attack at her. shelly, umi and shinju went after sandy and sango in the glass pillars.

"not so fast."whinto stopped them.

"move!"shelly looked to him.

"ready umi?"shinju looked to her.

"yeah!"

those two got back to back and sis their 'rising wave' pitch voice at whinto who deflected it toward sandy's glass pillar. Then he slipped his staff in his hands around some not notching the crack forming in sandy's glass pillar and at blasts at the three girls laughing as they match him blow for blow each time.

CRACK!

"WHAT?"he turned to sandy free of her prison.

"umi!"shelly shouts to her.

"on it !"she runs to sandy.

"NO!"he blasted at her.

Then shinju and shelly in pearl idol form got together and them with their 'splash dance' pitch voice that deflect his 'raging hum' song blast at sandy and umi. Sandy opened her eyes as umi checked her clam wing pendent. The pearl was gone from it as it rested next to the aqua marine pearl upon a throne's arm rest. As umi with sandy still half out it ran over toward coral and mizu who were weakening mila.

"here !"she hands them sandy.

"bad viel!"mila tried aiming at umi.

"friendship bonds!" coral and mizu deflects her attack with it.

"AAAAH!"she is knocked out.

"three down one to go ."mizu smiled.

Sandy was fully awake now summoning her pearl to her self as she became orange pearl voice taking a place among her friends. The last person they had to free was sango who laid behind whinto who wasn't giving her up at all. So he turned his staff into a short sword and came charging at coral full of rage, but acting on her feet sandy saved coral and the other only to get stabbed badly.

"SANDY!"they all yelled.

"i am fine ."she started to bleed out.

"DAMN IT!"whinto turned his staff back .

"you dead!"coral was mad.

"you fish food!"umi joined her.

"let end this !"mizu was holding the weakening sandy.

"yeah lets."sandy barely could speak.

"altogether now!"shelly wiped her tears away from her face.

before the girls could launch and whinto counter attack a bright light came from one their pearls taking the form of aqua regina. The glass pillar holding sango diapered as she came to and took her idol pearl form by her friends. Whinto was frozen in placed as his staff lost its power along with him when he was face by aqua regina.

"my creatures of the sea stop warring against one another."she begged.

"the whales will be freed once more."whinto broke free.

"WHALE!"the girls were puzzeled.

"THOSE DAMN HUMANS HUNT US DOWN AND KILL US FOR SPORT!"yelled whinto.

"oh...!"the girls looked at one another.

"so you wanted the seven seas to be yours to control." aqua regina guessed.

"yes!"he shouted.

"sandy!"sango yelled out.

She was slowly dieing with no where to save her as aqua regina waved her staff over her saying she'll rest on the land where her father came from. Whinto hits the ground with great pain running through his heart. Shi-shin the appeared in her Hippocampus form above their head on the sky light waiting for them. So aqua regina teleported sandy's dead body to shi-shin's back side as the girls and whinoto make some peace between them.
