I have my own Sherry the Mouse story. I realized that having a character that could skip portcullises would be useful, so I kept her. I had to make her tougher and I found a way to grind to raise her stats. I gave her a lightning wand (one of the few weapons she could carry), went to a village and found a dog walking around, and had her kill it. In order to get it to re spawn, I had to remove the dead dog body, but it was faster to just put it in my backpack. So I would have Sherry kill dogs until I ran out of room for the bodies in my inventory and then go far away to unload them, then go back and grind some more, shooting dogs with lightning. Once she was strong enough to hold a real weapon, I went to the cave of the giant ants and had her kill ants with a halberd until she was strong enough to wear plate mail armor. A mouse. With a halberd and plate mail armor. Probably my favorite gaming experience ever.
