display images randomly from the bottom line

Can anyone help me? I have a school project. One of the problems is that i do not know how to display images randomly (some mice) that starts from the bottom and they walk up the screen. The mice should have different colors and their starting point should be different. The user should click on the mice to gain points, and then the program should sum these points. Can anyone give me an idea??



What have you tried so far?  Post some screenshots of what you've done so we can guide you a bit.

Obviously, you'll need a canvas and some sprites.

Have you done ANY of the tutorials?  If not, how do you expect to program an app to do these things.  So, first do the tutorials... The tutorials are located here: http://appinventor.mit.edu/explore/ai2/tutorials
