Mob Signs

You can use Mob Signs to spawn mobs. There are two types of mob signs:

Each mob sign has two required lines. They do the following:

The first line is the type of sign ([mob]).
The second is the mob name. You can see the list of valid mob types here.
The third, optional, line is the number of mobs to spawn. This can be an integer (4), or a range ([1;5]). With Mob Count:

[mob]
frog
