River Bed is an Advanced Difficulty track in Bloons Tower Defense 4. The MochiCoins description of this track calls it simply "Stream Track". The track is wide, allowing multiple bloons to move side by side along the track.


  • The track appears to be in the shape of an Omega symbol.
  • Since bloons can move side by side, sometimes more than one bloon will enter at a time.
  • It looks like a dried up river.
