I assume that you are referring to the Ten Plagues in Exodus. In order, they are:
1) The plague of water turning into blood
2) The plague of frogs
3) The plague of gnats
4) The plague of flies
5) The plague of livestock death
6) The plague of sores
7) The plague of hail
8) The plague of locusts
9) The plague of darkness
10) The plague of first-born death
Several plagues
frogs and flies
God sent Plagues.
If you're referring to the Stephen King movie, The Mist, then: there are no plagues. The creatures are from another dimension.
Moses didn't send the plagues. God did. But I believe that the death of the first born would be the worst.
Frogs were used in the plagues.
God made pharaoh the 10 plagues.
God killed them
They continued in their idolatry.
PLAGUES
In the 10 Plagues (maybe)
There were a total of 10 plaques in Egypt , sent by God.
