Monster Mistakes of Yesteryear - The Killer Penguin

In 1985, when I was an impressionable 13 year old, someone gave me a copy of Dragonroar RPG by Standard Games.  

I remember it not for it's qualities as an RPG but for one hideously bad monster idea.  

The Killer Penguin...

The Killer Penguin Miniature???

Now I'm not one for dismissing people's creations off hand, but come on guys, what were you smoking that day?  Needless to say no-one's arguing over the rule changes between Dragonroar 3.5 and Dragonroar 4e so the RPG itself was neither a commercial or a critical success and it has long sinced disappeared into RPG obscurity.  

However, I do think that we need to preserve the memory of the Killer Penguin as a warning to all the misguided monster makers out there who may be toying with nature.

If you can think of any other more catastrophic monster mistakes or you think that the KP is much maligned feel free to write to the usual address...
