Forum:Crystal Beast Pendulum Summoning Ruling

so here's the question of the day, and I'm hoping you guys have a good idea on a proper ruling for this.

I've pendulum summoned Crystal Beasts Ruby and Sapphire, after the summon, their effects kick in. I think one of these effects gets their timing missed, but is it possible to chain their effects to add a CB to the back row, then summon it to the monster zone?
