Why was Whitebeard in Rocks?

[SSJ2]

WB was shown early into his pirate life not caring about fortune, fame, or anything of the sort. It strikes me as odd that he would join a group of insane but powerful pirates. What was he getting out of it?

 

[Fantastische Hure]

Because he doesn't like grass.

 

[SSJ2]

Is that why they stay in boats?

 

[Fantastische Hure]

Yeah.

Rocks > Water > Grass/Earth

 

[Future Warrior]

Can't say I have a clue.

 

[Fantastische Hure]

Because he doesn't like grass.

 

[Future Warrior]

Maybe he lost in a Davy Back fight.
