Lol. Here's are pics of the Gigantoad just outside Bastok. Bastok was the first country to beat their enemy, it took 8 hours, and hundreds of people fought in that time span.

Unfortunately there are no San d'Orian pics of the Gigantoad, but they defeated their monster shortly after Bastok did.
And now for Windurst, well the pics speak for themselves... btw, Windurst was never able to defeat theirs. Lol.

If the pics don't work when you click on them, copy and paste it into your browser rather than clicking.
