Trouble with instances

I have a flower that needs water every "x" seconds. This is indicated by spawning a small waterdrop object to an image point on the flower. I click the watering can and then click the flower. The waterdrop object is then destroyed. The problem is that it destroys all instances of the water drop instead of the instance that is associated with the clicked flower. I've tried several setups with instance variables, but my brain isn't connecting the dots. I wonder if anyone could help me out here? Attached is a stripped down version of my file with the problem. Thanks!

You're not picking any water instances, so by default they are all picked for destruction.

this will work in your case. You could also make one a container with the other in which case your original code would work.
