Incest and/or impregnation of any characters (female if they're to be impregnated) from any animated movie featuring anthropomorphic characters. I'd especially like to see something from any of the "American Tail" movies, the "Rescuers" movies, or something from that era of animation, I miss that style so much.

I haven't seen those movies in years! I should really watch them again sometime.

Everybody should. Nostalgia isn't a bad thing and the older stuff tends to be the most beloved.
