This takes place when Chopper just joins the crew, and you had been a crew member since Zoro joined, have fun ;P

When Chopper got onto the ship Zoro: oh so your a doctor? He asks while looking at the small and shy reindeer doctor

Nami: she nods

Luffy: wait... Chopper's a doctor? Luffy tilted his head

Nami: what did you think he was when you asked him to join the crew, dumbass!? She glares at her rubber idiot captain

Luffy: he thought for a moment a cold transforming reindeer monster thingy

Sanji suddenly spoke up, staying calm like this wasn't a weird thing to say at all Sanji: emergency food...
