Spawing Random object on Start Of layout

I've got an array called objects

contains say monster 1 and monster 2

I've 2 objects setup called monster1 and monster 2

How would I pick a random monster from the array and display on the screen at the start of the layout.

Thanks

You would need to create an if statement picking the correct monster.

OR you could put all monsters in a family and pick a random family member.
