I'm just waiting for pluton's reveal.
IMO, Pluton is powered BY the electromagnetic force in Mt. Fuji. Kind of like discount motherflame.
I think Kaido and Linlin are just floating around down there with the Ancient Battleship, bathing in lava.
But i've tied Drunk and Hungry returning to Pluton's activation too much, when all they really need to escape the volcano is a strong enough eruption to knock them back out.
There's a Big Mom Knock Up Stream Pregnancy joke in here somewhere.
