Oh, well, if it's not too much trouble, sure! [He glances around at the measuring cups and equipment set up and makes a pretty safe guess.] It's not too different from chemistry, is it? Or mixing up medicines? I at least have some experience there! [He jauntily tosses an egg from one hand to-- OH NO HE OVERSHOT-- oh no wait he catches it with a bandage-- oh no wait as he snaps it back to his hand he inadvertently crushes it. WELL AT LEAST SOME OF THAT WENT AS PLANNED.] O-oh, eggs are more fragile here. Uh. Sorry, I'll keep it simple from now on. [He shoots Jesse a very apologetic look and rinses off his hand in the sink.]
There is no One Piece canon justification for eggs being tougher there. EXCEPT THAT EVERYTHING IS.
