"Hey guys!" Rikki said welcoming her friends to her café. "How are you?" she said then Cleo and Lewis started off talking about how things have been with them while everybody subsequently did the same. After they were done saying how they are Jake came out of the office where he has the desk that used to belong to Zane and he said "Guys, today's the solar eclipse anybody up to taking a look? It should be starting pretty soon." then they all agreed not knowing that this solar eclipse is different than any other solar eclipse. Why you ask? Because the moon that is eclipsing the sun today is a blue moon. Let's see what happens… as everybody filed out to look at the solar eclipse each merman saw the eclipse but also saw the blue moon covering the sun and instead of the mermaids getting moonstruck this unusual moon caused the mermen to get moonstruck. Soon the four mermen started acting strange. Lewis was watching a kid flying a remote control plane and said "Oohh, loopy loopy" and Cleo responded with "What did you say?" then Lewis pointed at the plane and lightning fell from the sky and hit the toy causing it to crash and burn and Cleo looked at him with shock as he laughed and said "Bye Bye plane!" and ran off acting like a crazy person then each of the mermen also acted strange in various ways and the girls stared at them in stunned silence until Rikki said "Are they…moonstruck?" then Rikki, Cleo and Bella ran off after them and Emma decided to go back into the office computer where she could access the book and do some quick research and found out about the fact that today's solar eclipse falls on the same day as a blue moon and looked it up in the book and found out why the mermen were moonstruck and used telepathy to tell the other girls "Hey girls. It turns out this solar eclipse is also a blue moon. That's why the guys are acting strange. The book says during this eclipse only mermen can get moonstruck but it ends when the sun goes down and the full moon rises and the fact that we already saw the eclipse prevents us from getting moonstruck tonight." "Okay so what now? Cleo asked "I think we should catch the guys and take them to the moon pool and tie them up there." Rikki said "But can't they use their powers without using their hands?" Bella replied "Let's just hope they don't remember that." Cleo said "What if they do?" Bella asked "Well I guess we can just knock them out so they don't use their powers." Rikki said then they all ran off after their boyfriends and Rikki found Jake and said "Oh Jaaake" and Jake turned around and Rikki ran off luring him to the water where they swam off and then while underwater Rikki grabbed his hand and dragged him behind her to the moon pool and when they surfaced they kissed and Jake came out of the kiss smiling then Rikki punched him under the chin and knocked him out and dragged him out of the pool and dried him off and used ropes to tie him up. they'd stored the ropes there for when the girls get moonstruck and the guys have to catch them and do the same to them.
Meanwhile at the park…
"Hey Ash!" Emma called and ash turned around and said "EMMIE POO!" and outstretched his arms and Emma stared at him in surprise as he charged at her and she said "Emmie poo?!" then Ash picked her up and ran with her in his arm to the beach and jumped in the water and took her to the moon pool where they surfaced and saw Jake lying on the ground tied up and unconscious and Ash said "What-" but was cut off when Rikki froze a ball of water under his chin and made it hit him on the chin and knock him unconscious then Rikki and Emma tied him up next to Jake. After they had Jake and Ash knocked out Emma decided to help Bella catch Will and they succeeded pretty easily and soon Will was out cold and tied up next to Jake and Ash and then Emma, Bella, and Rikki went to help Cleo.
Meanwhile at the beach…
"LEWIS STOP IT!" Cleo said and saw Lewis creating a huge storm with lightning flying everywhere and she used her powers to sent a burst of air at Lewis and lewis did the same and the two gusts collided and Cleo and Lewis did this for awhile until the rest of the girls got there and Rikki used her water powers along with Bella's power to attack Lewis while Cleo used her water powers with Emma's ice powers to attack lewis from a different direction and Lewis tossed lightning at the ice tentacle while the jelly tentacle came from behind to grab him and bring him into the water and take him to the moon pool where the four mermaids knocked him out and tied him up there.
Later that night…
"Alright girls the moon has risen so let's wake up the boys." Rikki said and they untied the boys and Rikki made several balls of water and made them ice cold and tossed them at the boys and woke them up and soon all four mermen were woken up with tails and Jake said "WHAT THE HELL?! Why am I in the moonpool cave?! And why do I have my tail?" the other boys reactions were varied to say the least but then the girls explained what happened and the boys were shocked to find out they were moonstruck and Lewis was surprised at his behavior while he was moonstruck and apologized to everybody for causing trouble. The next day everything went back to normal except for a certain surprise.
