(SPOILER)If the Malboro is Lvl 1-29, it will inflict high damage and many bad statuses if it is eaten. If it is lvl 30+ it will increase the character's spirit by +1. I bet you are using the official FF8 strategy guide for you questions, are you not?

Also, with the new spoiler tag rule, does this mean that now everyone who answers the question correctly will get a point, since now they would be unable to read someone else's answer and copy it (since this is why I thought you made it so only the first person to answer correctly gets a point).
