Poison?
Hey guys! Look, lots of people are talking about the whale, others saying no...
But the way I see it, this is THE perfect opportunity to take out the monster, with little risk to us.
The monster's big, right? It needs to eat a lot, right? So, why not poison the whale? I don't know where we'd get THAT much poison, but we have a whole city, we've gotta find something, right?
Besides, likely, this would be harder for the monster to link to us than, say EXPLOSIONS.
