Marcy And Alena And Marcy (Patreon)

If you're just now joining us for Kae's Amphibia Headcanon But It's Just Yulivia, Marcy and Alena Newton are Yunan and Olivia's adoptive daughters (a mudpuppy and hellbender, respectively).  Marcy Wu was Yunan and Olivia's favorite human of the Calamity Trio, to the extent that they see her as their third erstwhile child.  So here's Human Marcy meeting and interacting with her little sisters.

If you haven't seen the canon, Flipwart is amphibian chess.  Marcy was the only creature clever enough to beat the king at the game.  I assume Olivia is good at it too, because she smert, and intelligent people play chess.  I mean Flipwart.  It's a good thing when the student surpasses the teacher, Liv!

And yes, Marcy would be geeky enough to call back old Simpsons jokes.  Maybe she had help from a little magic box!
