Remember Secrets of NIMH? It's on the cartoon channel right now. Don't judge, I'm waiting for coffee to brew. Coffee is a grown up thing. And I'm stalling because my dad is waiting for me to help clean the windows and paint the porch. Can you blame a girl?
Anyway, NIMH. I don't remember much about it, but I remember being scared. Fun Wikipedia fact: "a 1982 animated film adaptation of the Newbery Medal-winning book Mrs. Frisby and the Rats of NIMH (Mrs. Frisby's name is changed to "Brisby" in the film due to trademark concerns with Frisbee discs.)
Hm. Those mice look awfully like the mice from An American Tale.
