Shriekmaw vs. Ichorid

[Tog]

I'm playing against Ichorid with two Narcomoebas in play with several Bridge from Below in the graveyard. I evoke a Shriekmaw in to play. Here's where I get confused. Would the opposing player receive Zombie tokens for the dying Narcomoeba? What does the stack look like when you evoke a creature with a CIP ability in to play?

Thanks in advance,

The Shriekmaw coming into play has two Triggers. The "sac me"-trigger and the "destroy target"-trigger. As you control both, you can stack them the way you want.

If you stack the "sac me" trigger on top, your opponents Bridges will long be removed, when his Moeba dies.
