// DrunkenFratGuys collectively decide on one random location where there will
// be a "party" on the critter map, then they all go to that location, moving
// north and then east until they reach the party's location.
//
// Since we want all the frat guys to go to the same party, the party's location
// is represented as a set of static fields.  Normal fields are replicated into
// each object, but static ones Static fields are shared throughout all objects
// of a class.  This is important because all frat guys want to go to the same
// party.
