Question

why can't he play football or shape a snowman

Answer 1

Beacuse he had no arms and legs.........

Answer 2

I think the boy doesn't have two legs for which he can not play football.

Or

He doesn't have his arms so that he can't shape a snowman.

Because if you want to play football then you need to have legs. But he did not.

In the same way, If a snowman is to be created then the hand must be necessary. But the boy doesn't have that too.
