After doing that one quick redesign of Salacia's Royal Design, I'd finally decide to pick up the chance to draw their own Kids again (since I've always desired of wanting to draw something for the Family of King Poseidon's New Life in my AU.
So since that in my Re-written version of "Sponge On The Run" has a much better Redemption Arc for the Antagonist that isn't rushed where his Disguised form is actually his True Self & hasn't grown into Elderhood yet.
In my AU, Deities still stay young but when their come of death has come (meaning that they are secretly Mortal in the World of SB in My HC), they tend to fade into Dust & Become the Stars in the Universe's Galaxy like the Zodiac Signs (either when they reached to Old Age or Can Get Easily Killed or Something, I dunno, Cartoon Logic).
This takes a Few Years after the Events of the Ending in My Version of the Third Movie where Salacia gets pregnant & they ended up having a Few Heirs. Since Poseidon has already changed just like the Original, he ends up becoming a Proud Father while also spoiling his own Children for Love while also that He and Salacia start to become even more responsible rulers of their Kingdom when they entered Parenthood.
(But yeah, not to mention, during their first steps of "Parenthood", things already become a Quick Disaster for their Kids when they begin to cause mischief as Chancellor would be the one have to take care of all of his Bosses' heirs).
I've also decided to change Poseidon's hair a bit in my New Artstyle, since in the Original he actually had more of a Dark Purple Hair despite that I always did made his Hair Black based on some Marketings, as well as their own Raven-Haired Daughters.
