Dead monster spawning more monsters?

[Twin Matrix]

Is there a way to put it so that when a monster is killed, it spawns more monsters?

My problem is that the monster that gets killed is the only monster in the battle, so if I put a battle trigger on his HP for 0%, the battle will end before the other monsters can spawn.

I'm not sure how do to this.

The idea behind it is that you fight a Heart-Shaped Chocolate Box, and then when you destroy the box, it spawns a group of chocolates.

Thanksss~!

Give the box, say, twice as many HP.  Then an event triggered when it's at half HP, which will bring in the chocolates and destroy the box itself.

Wow.

That's so brilliant yet simple that it puts me to shame. o-o

Thanks!!

Bear in mind that if it's hit hard enough, it won't split open.  Ten times as many HP might be more prudent.
