Is this going to be an Etoy project or a Smalltalk one? If Etoys, then 
you might want to look at the examples at squeakland.org, and also 
subscribe to that mailing list, which is specifically aimed at using 
Squeak in education.

Specifically, the "Stair" example from 
http://squeakland.org/kids/sqfest_2004.htm could give a hint how to move 
a lemming. Instead of erasing, you might use a large pen to draw in the 
background color. To make the pen trails appear on top of the drawn 
landscape, you might put the lemmings in a transparent playfield.
