"We're trying to figure out what's causing Luffy to be so sick. I'm thinking it was something he ate. But I checked what we've eaten in the past two weeks and there wasn't anything poisonous in there." Sanji said, looking through his cookbook.
"If it wasn't anything poisonous, maybe he had an allergic reaction to one of the foods he ate." Robin said with a confused look on her face.
"It wasn't that either. I would have known if it was any sort of allergic reaction." Chopper said, putting a fresh towel on Luffy's forehead.
Everyone just sat here in silence for a minute or two until Chopper said "What if he got bit or stung by something!"
The StrawHats all looked at Chopper as Usopp got up and went to look at his book of plants and animals.
Sanji also started looking through his cookbook to see if there was anything that could have done this to Luffy.
"I've got it!" Usopp said, showing his book to the others.
"While I was training and using plants with my slingshot, I came across a plant that looked exactly like a rose but it actually was a deadly plant that produces invisible gasses when it feels threatened.
Those gasses can lay dormant in your body for up to two weeks before taking effect.
I gave it the name, the Dead Man`s Rose."
Everyone in the room was shocked at what they had just been told until Copper said "If I can manage to find that rose, maybe I can use it to make an antidote!"
"Let's find that rose and save Luffy!" Franky yelled.
"Yea!" the rest of the crew yelled in unison.
