Beastly Behaviour - The Dog
Don't be fooled kids by the bright colours! "Beastly Behaviour" was an adult animation that was screened on late-night Channel 4 in the mid-90s. Not all of the episodes are on Youtube (There's a cat one too). These 1 minute plus animations, feature the very different way animals and other beasts like marine life, have male-to-female mating. The animations are crude, but the narration is pitched in the style of a wild-life narrator, and if your not aware alot about animal biology and how they mate, well many of the facts may astound you, as they're all true. The show was produced by eggtoons, which has it's own website, but the main brains behind it is Andrew Wyatt. Wyatt was a freelance animator who had worked on such well-known cartoons like the Ninja Turtles and the Ducktales movie for Disney. He joined Honeycomb animation, and produced this obscure classic.
4 episodes feature on Youtube, but I'm sure there are more. Rodents, Mantis and Marine Bristleworm are the other 3, however I feel this Dog one is the funniest of the lot, and the least gory. I like the dig at humans in this one too. This is definitely not for kids! The Mantis one is probably the most gory, as true to life, as the female bites the male's head off, as he is having sex with her. Thank god that doesn't happen in humans, I'd be a virgin all my life then!
