This is probably the only group of Necromorphs you'll want to run into. Small and child like, they come in packs of roughly 15. They can easily overwhelm you, but are normally killed in one shot. Each and every one of them contain an item, so they're basically a walking free store for you to take full advantage of.
Pulse Rifle would be your best bet with these. Just aim and shoot anywhere on their bodies to get yourself a kill. Only one bullet is needed, so as soon as you shoot, release the aim button to conserve ammo. Don't let them sneak up behind you.
