 Norwood said in January 2011 that Fatboy has developed over time and is continuing to develop , with more sides to his personality being shown . Fatboy 's caring side is shown in several EastEnders scenes , most notably his friendship with Dot , and a scene where Fatboy and Mercy bring a cake to Kat Moon ( Jessie Wallace ) after her child dies of cot death . Although Norwood said in January 2011 that Fatboy will always be a joker , he felt it was good to show Fatboy 's softer , more intelligent side , saying that the character 's " street " side drops quickly when he is around Dot and Mercy . Norwood said that Fatboy wants to improve himself , but fears that showing his caring side in London will get him beaten up .
