B2 Went for Amazing Race

B2 and two of his friends went to Amazing Race in Pulau Ubin.  He is exhausted by the time he reached home.  He did not complete the race finishing 7 checkpoint.  He has fun describing his day to his two brothers.  The checkpoints are quite difficult as there are swimming, kayaking and jumping off 3 storey high into water.  I hope he had fun and plenty of chance to share his adventure with his friends.
