Eighth Plague: Locust Clouds

Destroy up to 3 lands.
"I will bring locusts into your country tomorrow. They
will cover the face of the ground so that it cannot be
seen. They will devour what little you have left after
the hail, including every tree that is growing in your
fields. They will fill your houses and those of all your officials and all the Egyptians; something neither your fathers nor your forefathers have ever seen from the
day they settled in this land till now." Exodus 10:3-6
