Title: Poisonous mushroom?

Yamashitae: Sad times are exactly when you should chow down on mushrooms-! Go, go~!
Rough Cocklebur: Are you ok?
Yamashitae: On my previous mission I failed really badly~ Ahahahahaha!
Rough Cocklebur: Eh!? Why are you suddenly laughing...
Rough Cocklebur: <Now that I think about it, I've heard about a poisonous mushroom that makes you laugh uncontrollably when you eat it.>
Rough Cocklebur: <What should I do...? Should I use my whip on her back to make her throw them up...?>
Yamashitae: Aah~ Mushrooms really are delicious~! I didn't even notice when I started laughing.
<Yamashitae: Would you like some too, Rough Cocklebur?>
Rough Cocklebur: That was so misleading!!
