This story is all about Mr Happy and Mr Grumble. They had to find a hobby for Mr Grumble because he was not happy and grumbled all the time.
In the story Mr Happy and Mr Grumble meet lots of people with different hobbies. But Mr Grumble does not like any of them.
My favourite character was Mr Rush because he likes driving fast cars.
At the end of the book, Mr Happy finds a hobby for Mr Grumble. It was fishing because he grumbles when he is fishing.
This was a fun book to read.
