[Must be cookies. Marco can make cookies too! Like little bird ones even!]

Hah. I don't know the first thing about training kids. I'm not exactly Garp, eh? But if you want to try to spar, you're welcome to try. [So long as you don't mind that Marco will be basically, doing all his normal things like cooking or standing there reading a book and letting Sabo come at him and then just treating him with kid gloves on and dodging as much as possible. It'll be like Ace's attempts to kill Whitebeard. Which might be bad for the ego.]
