Critter Exploding

When furiously clicking a critter, it explodes. How do i prevent this, but still maintain the Stats - Race: Critter?
What i want is a "shop that is a unit" to talk and show a respond when clicked on.

I do not want to use a click detection trigger. I do not really need this, but it would be nice to give players a better gaming experience.

As far as I know, that's not possible, without the trigger you mentioned.

Why does your shop need to be a critter? There is probably a better way to do what you need.

Example: If you just need the model of it then just make a unit or building and change its model file to the critter.
