On a sunny riverbank in a city park, a group of otters has formed a street band. Their instruments are quite unique: one otter claps two clamshells together as cymbals, while another taps on different-sized river stones floating on the water like a xylophone. The star of the show, however, is the "Bubble Master," who uses a hollow reed to blow a series of giant, iridescent, crystal-clear bubbles. A flock of pigeons and squirrels, their loyal audience, sits along the bank, bobbing their heads to the rhythm. The lighting is warm afternoon sun, casting golden scales on the water's surface, creating a relaxed and joyful atmosphere.
