|Standard effects:|| 75hp injury from sheep (max.), Large crater|
30hp injury per missile (max.), Small crater
The Mega Sheep acts exactly the same as the Super Sheep, except for the fact that it can drop 3 missiles by pressing the Spacebar (or Enter on the Ninja Rope) while flying. After all 3 missiles are used, pressing the Spacebar will make the sheep drop down and explode on contact, like the Super/Aqua Sheep would.
