In elementary school (early 90s) my school's computer lab had this game. Here's what I remember:

-I believe you played as a TMNT
-It all took place inside a building. You could walk left and right through the floors and take an elevator up or down at the end of each floor.
-There were closets where you'd sometimes find an electric eel-type creature that would zap you.
-It may have had some element of crime investigation to it, or arithmetic, or something generally educational. Not sure.

Anyone know what this is?
