For me, a sequel to Secret of NIMH isn't such a bad idea. To me, the first one was over too quickly. It's more the way the sequel was carried out that irks me. Direct to video, a juvenile title (Timmy to the Rescue), song numbers left and right, an annoying caterpillar, and, for some reason, underwear. They talk about wearing underwear, and they don't even wear any pants. They all wear nothing but their fur from the waist-down. If you don't think it's nonsense by that point, you were probably born around when the GOUT was released.

BTW, you've got a funny (read: humorous) name, Monolithium. Kudos!
