I say forget Petra loa. I know that the next breeding event has baltasar but the monster doesnt look remotely like baltasar. I say forget petra loa use some other monster. If you need to pospone this event and instead do a balatasar and crissandre, first of all, they look like they could date. Second of all, baltasar and crissandre would be a really good monster. Imagine and aoe stun. And an aoe bleed.

With that said, what does their looking alike have to do with anything? Other than Galante Jr when has that mattered?
