Mr Oily and the Runaway Lawnmower

Mr Oily is a delightful four year-old boy who likes nothing better than taking mechanical things apart and putting them back together again - with varying levels of success.
Mr Oily, as he is affectionately known, normally has blotches of oil and dirt all over his clothes, together with a rather grubby face. He has a kind heart and loves to go on whirlwind adventures with his fellow petrol head buddy, Grease Monkey. Oily gets more than he bargained for after tinkering with the family lawnmower, again.
