Prevent it by dealing with the source of the moisture, which is likely the shower if it's only in the bathroom. If you have a bathroom exhaust fan, use that during and after showers. Opening a window can help if you don't have one.
When my vent fan died last winter, I used a small dehumidifier because the moisture got really bad. Dehumidifiers take a fair bit of energy, but that energy is converted to heat, so it's basically the same as using electric heat.
I was thinking "Mr. Pizza Hut" was some kind of mascot(which I guess gorby kinda is). It made sense to me because there was a Nintendo game with the Domino's mascot.
