パラメディック「エゾテングダケをキャプチャーしたのね
地面に生えていると思うけど、毒を持っているから食べないようにね。
もし食べたら、吐き気に腹痛、下痢などの症状が出た後、最後には肝臓や腎臓がスポンジ状に壊死して
死に至ると言われているわ」

タクト「それは恐ろしいですね」

パラ「でしょう？」

タクト「ええ、で、味は？」

パラ「……は？」

Para-Medic: I see you've found some fly agaric mushrooms.
You'll find it growing on the ground, but it's poisonous, so don't eat it.
It says here that when you eat it, the initial symptoms include nausea, stomach pain and diarrhea. Finally, your liver and kidneys will break down into a sponge-like substance and you'll die.

Tact: Sounds like a horrible way to die.

Para: Isn't it?

Tact: Yeah. So how does it taste?

Para: ...Huh?

(Fly agarics/[i]Amanita muscaria[/i] aren't [i]that[/i] toxic, though it's not uncommon for them to be erroneously described as such in field guides published in the time period of MGS3. Still not a good idea to eat them in the field though, unless you're from a culture that knows how to prepare them properly.)
