_________________________________________
*Ocean Jasper cookie or originally Stellar Jade cookie, the reason why I change their name is because like the other gem mermaids where base on gemstones that related to the ocean so I change their name from Stellar Jade to Ocean Jasper and also ocean jasper has the similar color scheme as stellar jade.

*Lapis Jellyfish cookie or originally Floating Bell cookie, the reason I change her name is because before I knew about Floating Bell cookie existence I was going to create a jellyfish cookie oc on my own that was also base on the floating bell spotted jellyfish and has similar concept as her so I combine both into one.

If you're reading this please don't sue me. I just want to express all my wierd imaginations and I don't mean that Kyunika's story is bad I just think it could taken on a different route of narrative, please don't take this as an offence and if you see any sentence in the story or quotes that's off it's because I'm very bad at grammars. Please enjoy the story I make you can show your opinion in the comments so that I improve my story making better.
