Get the Moosemug. 
Moos is a truly unplaceble creature. Loves football and career mode. Kind of a sigma, doesn't chase but attracts. A Moos is likely to get absolutely sh*tfaced at any social function that he takes part in, ending up either knocked out on the ground or above the toilet. Moos is very tall but has a huge hunchback. Other than this he is the most honest and sincere guy you can meet.
