This is a Challenge in which you must beat Snake River Easy, using towers, traps, and agents that make ABSOLUTELY NO SOUND! Sound doesn't include the bloons popping. Also, you can't buy noisy upgrades, and no noisy bloons (Ceramic, M.O.A.B.-Class, and worse) appear. Also, to make it harder, you cannot mute sound or music!


  • The name is a reference.
