This is what happens when you're studying for finals.
I was just thinking, the Yeerks were lucky that none of the Animorphs were med students, or aspiring veterinarians that cared more about humans than yeerks.
Because I was just thinking, since Yeerks are parasites, what would happened if you just "poisoned" the water system with Immiticide, or heck, just dumped a whole bunch into the Yeerk pool? I wonder if it would kill them. Then again, depending on how big the Yeerks all, the amount of immiticide needed to kill the Yeerk might be a fatal dose to the human.
Also...Andalites must have a freaking iron-clad immune system...do you know how hard it would be to keep the lungs healthy without a mouth? They'd never be able to sneeze properly, they'd be inhaling everything.
Ok...back to studying for finals...freaking pharmacology....*mutters*
