Sisters Kacie & Zoey have a dispute to settle, so Kacie suggests they take it to Gunge or Get Gunged to battle it out and avoid the gunge tank. The two girls test each other's knowledge in a quiz filled with banter and taunts, both desperate to see the other face a messy fate. Unfortunately Kacie's plan backfires and a very smug Zoey ends up subjecting her to a freezing cold green gunging! Poor Kacie's hair is ruined as she shivers unhappily in the gunge.
