Drag and drop sorting help

Help! Having a complete brain freeze today.

I'm trying to create a drag and drop sorting activity where different drop objects appear one at a time that can be dragged onto 1 of 5 drop targets, with only 1 correct target.

I'd like the drop target state to briefly display a tick or a cross state depending on if it's right or not. If right, i want to exit animate the object to disappear, if wrong I want it to animate back to it's original spot to try again before displaying the next drop object.

Any help on triggers needed or examples of something similar much appreciated!
