Thanks for the answers, everyone. And no, it's not a rat swarm, just normal rats, since it's a level 1 party.
EDIT: Also, they've
NEVER played D&D before, so i won't try
too hard to kill them
Also, thanks for the counters, frankthedm. They're really nice
As for the rats being able to stay in the opponent's square, the DMG pg.29 says:
"Creatures two size categories apart can occupy the same space without special circumstances. Half the normal number of creatures can occupy the space as usual (fractions are not allowed)."
Thus, up to two rats can occupy the same space as another PC.
Same page, to support Dross's reference to the Rules Compendium:
"If a creature is in at least one of the spaces occupied by a larger creature when that creature moves out of that space without taking a 5-foot adjustment or withdraw action, then the smaller creature gets attacks of opportunity against the departing creature."
And finally, just something I thought was interesting, same page:
"Any time more than one allied creature occupies an oppenent's space (either in the same square on the grid or in separate squares), the allied creatures provide each other with the benefit of flanking. If a creature occupies part of an opponent's space, it provides flanking to all allied creatures outside he opponent's space."

), which includes rats. Since they are tiny creatures they have to enter the opponent's square to attack.
