One Piece 2nd Generation: Time Warp Part 16

Riker and Chrono get sent to a jail underwater. Under constant watch. "Well smart ass. How do we get out of this one?"

"Easy." Chrono's hands come from behind his back along with a blueprint. "Only you were put in sea prism stone. They dint know I that I'm a devil fruit user." A portal opens under them and they fall through it into a different time era, on the Oro Jackson...the ship of the King of The Pirates...Gol D. Roger.
