New to The good the bad and the munchkin

[TheJohan]

Hi, I'm new to this game, expecially to this expansion I just bought (altho it's my first) "The Good The Bad and the Munchkin" I had just one game so far but already have a couple of questions:
1)The game was won by a Sceriff who forced the vice-sceriff to help him (Sceriff card power), their combined score was too high for anyone to stop them, was that possible to do? Forcing another player to help you and getting the win from that?
2)We play the Italian version, so maybe this has something to do with it, but we encountered a level 2 monster called "Gattacicova" (Italian pun) but the description continues with this "you get treasures and level only if your fighting strength is lower then the Cattywampus, if it's higher you have to run"
We have several questions on this card, first is: what is a "Cattywampus" which we imagined could be the English translation that someone missed, however it seems to say that you can't beat her like normal monsters, you have to be lower then her, but it's a level 2 card o.O I'm quite confused by this.
Thanks in advance for the help ;)
