It only takes two, but the trick is getting them in the lightbulb.

None. Mice can't change light-bulbs as they are mere rodents without the physical or mental ability to do so. Not to mention it's much safer for them to pilfer food in the dark.
Just two, but more can join in if there's room in the lightbulb.
