Can you help me name this game?

Hopefully I've gotten the right newsgroup; you'll have to forgive me if I
haven't. For a while now, it's been in the back of my mind to try and
hunt down an old shareware RPG that I used to enjoy. The problem is that
I don't remember its name. I can tell you that it involved 2 or 3 kids
working to defeat this evil school teacher - something like that, anyway.
It was a while ago. You brought them into this 3d dungeon and you had to
find fountains and food along the way. Otherwise they'd pass out and be
unable to fight. You used flasks to carry water. I'm sorry that this is
all I can remember, but hopefully someone can help me. I also think the
game was on a CD packed with shareware called the 1000 Game Collection,
but I could be wrong. Thanks in advance for any help you can give me.
