Kim wanted to play basketball.  He was a good player, too.  But sometimes he didn't keep his mind on the game very well, and sometimes he made mistakes that disgusted the other boys on the Arrow's team.The trouble was that Kim didn't practice as much as the others.  Instead he took singing lessons and sang in the choir.  Some of the boys kidded him about that; in fact, they were pretty sore about it and blamed Kim when the Arrows lost.  No wonder it was hard for Kim to do his best.How Kim managed to combine the two things he liked to do is told with plenty of basketball action.
