It is about some like rodent like creatures that live in a community together and one day they are at school and some sort of like poison or something comes over their town and the children in the school flee leaving their parents there and they go on an adventure and I remember at one point they are like in a sewage system and it was a cartoon movie. I think the teacher's name in it was mr. mole.

Does anyone know the name? It is going to kill me if I don't find it!:D :eek:

Never mind! The name of this movie is "Once upon a Forest" and it was made in 1993!
