The brotastic triplets from Season 1 return to conquer a new course. Also playing with fire this episode: a trio of dads and three comedians.

A giant game room - flooded with a zillion gallons of lava, of course - challenges the guts and grit of kickballers, ballerinas and black belts.

The place: a haunted attic. The players: fearless moms and dads. The prognoses: magma mixed with a morbid side of mayhem.

A Kid's room provides the setting, but that doesn't mean this lava-filled course is child's play. Three teams will enter. Only one will prevail.

A team of improv teachers, a trio of best friends, and three roommates put their skills to the test in the hope of scoring the $10,000 prize.
