我也来给今晚的活动暖个场，我家七岁的老大自弹自唱，Underwater

 

Underwater there's a crab in a cave, watch him scuttle to and fro

See the seeweed give a dance and a wave as the tide begins to flow

Underwater is a world to explore, there the fish are swimming free

Treasures lying on the ocean floor, pretty shells for you and me
