How do I create known object between random objects

Hello guys, what I'm trying to do is create five instances of an object that has four animation frames, but I want one of those five instances (in a random order) to have animation frame number 3, while the others must have animation frame 0, 1 or 2 (random).

I created a .capx with the objects and a event that create five blocks with random colors (0, 1 or 2 animation frame) so you guys have something to start. I really have no idea how to do that, please help me!

Summarizing what I want to do:

Click button --> Create 5 blocks

one of the blocks must be green

other must be red, blue or yellow

Just make 4 blocks with frames 1to3, and one more, that is always frame 0.

lol thanks that was quite simple

the example i used its not exactly what i'm trying to make but I thought it should work. it's a little bit more complicated than that, I will try later to see if I can achive what I want. If I can't than I'll be back hehe

Thanks again
