After awhile of looking everything over and Jessica not finding anything she assumed both she and Amber could both do "why not try being mermaids?" Amber suddenly suggested, shocking Jessica.
"huh...? but...isn't that...I mean-" Jessica simmered in surprise. "too girly?" Amber interrupted "be honest despite what I'm guessing you thought agreeing to not gender flipping was easier done then said", the response leaving Jessica more surprised, "plus realistically mermaids aren't all just singing atop rocks and being pretty. theirs the endless undersea exploration, advanced swimming not doable with legs, immunity to deep water pressure... those are the things I'm more interested in doing if I was a mermaid" Amber then listed. "...OK then" Jessica accepted.
Soon at reception "have you chosen your theme?" the receptionist asked. "yep, we're going for mermaids" Amber assured. "as stated in the new sixth rule that is indeed our selection" Jessica confirmed. "in that case this way please" the receptionist requested before escorting Jessica and Amber away.
Before long both mother and daughter were inside this area with a massive moonpool and hangers holding various blue scales bikini tops that Amber quickly went rummaging through "are these tops required for underage guests?" Jessica asked. "regardless of age in mermaid cases you'll soon find out" the receptionist answered as Amber found the top of her size alongside one for her mother. "so how dose this transformation work?" Amber then asked. "give me a moment to get the formula ready. you can both use the time to get changed into your bikini tops" the receptionist answered.
a while later with both Amber and Jessica changed into nothing but the bikini tops with Amber floating within the moonpool while Jessica merely sat on the edge "Miss Randell, I must-" the receptionist started as they returned. "I told her to wait by sitting down but she refused" Jessica apologised by interrupting. "actually I was going to say how surprised I am over her catching on in certain required aspects as for safety those becoming mermaids are asked to get into the water first" the receptionist corrected as he handed each a glass of yellow liquid "now please drink up".
Jessica merely stared at her glass in curiously over this step while Amber without getting out of the water but leaning on the edge chugged hers' down, "no taste.... so what-" Amber started before the feelings of being charged hit her...
...the top Amber had on changed from whatever material it originally was into real blue scales while fusing to her chest, her legs locked together under the water as similar scales started forming. "Amber? are you OK?" Jessica asked. "ohh... more then good" Amber cheerfully answered as her skin between her legs started fusing together into a single limb before getting covered by scales, then the process reached her toes sticking out from her tail's end coursing then to lengthen out and split into branches as a light-blue membrane grew between then to create a tailfin while her lungs altered to allow the metabolism of oxygen from water.
"ohhhh... that felt... FANTASTIC" Amber called out joyfully as the process ended. "alright Jessica if your daughter can do it so can you" Jessica insisted as she downed her drink and went through the same process.
"GGGGOOOOODDDDD...that's a kicker" Jessica ousted once her process was done. "there should be a guide for you waiting at the other end to help you get used to your forms" the receptionist then assured "have a nice stay". "thank you" Amber welcomed as she and Jessica dived down and swam off:
