Mother Caramel & JoyBoy

Could there be a link between these TWO characters..?
Mother Caramel & JoyBoy are TWO big names in One Piece..

Could Mother Caramel & JoyBoy knew each other in the past..?

Before this..
I predict that Big Mom got one of her dream from JoyBoy's philosophy..
The Utopia that she create in WholeCake Island where all races unites under one roof..
Maybe Big Mom got that knowledge from JoyBoy directly or she hear it from other character..
Since Mother Caramel been revealed in Chapter 861..
I think that Mother Caramel is the character that got JoyBoy's philosophy to work in WholeCake Island..
Her dream to create an Utopia where all races unites under her power is what Big Mom carried on after she was gone..

What happen to JoyBoy..?
Remember that he promised Fishman Island to bring all of them (Mermaid&Merman) to live with human at surface..
Then he never come back..
I predicted in my last post that Big Mom maybe captured JoyBoy..
But what if that JoyBoy meets Mother Caramel (look back at the location between Wholecake Island and Fishman Island)..
And how easily Big Mom take cover of Fishman Island after WhiteBeard died in MarineFord..
So..
What if JoyBoy trying to get himself back to Fishman Island from somewhere (maybe his hometown)..
He want to lift that Noah Ark with the help of Poseidon..
So that he would take all of Fishman Island's people to the surface and lived with human..

Yeah..
The philosophy is the only reason I got right now to tied Big Mom or Mother Caramel to JoyBoy absent..
Other reason is World Government captured JoyBoy since Celestial Dragon want to slave Mermaid/Merman so badly (as what happen in Shabaody Archipelago where Celestial Dragons try to buy Camy the Mermaid at Auction House..)

I think Mother Caramel is someone to look forward..
She's more villain than Big Mom since she might be the one who control Underworld..
Maybe all Underworld's Emperors are puppets for her..
She can direct them to do what ever she wanted to do..
She also controlling Big Mom..
Yeah.. She maybe not in WholeCake Island..
But mentally she controlled Big Mom..
Big Mom like the children that fear her parent..
She would cry loudly as need attention from her parent..
In this case her parent would be Mother Caramel..

What you guys think..?
Please comment below.. ^^

For me, TWO things that possible for happen in this WCI arc:
i) Big Mom that we know is just one of the Incarnations due to Soul DF ability.. Whether Big Mom is somewhere else in WCI (maybe in the 4th floor infirmary) or the real Big Mom is Mother Caramel..
ii) Kaido will invade this arc and kidnap Pudding.. I just hope that Big Mom will want Strawhat Pirates to help her since Sanji maybe fall for Pudding a little bit.. A Temporary Ally is what I think the best for Big Mom & Strawhat Pirates..
