Or failing that a Tom and Jerry , Lego (or any Lego character like Lego Star Wars/Indiana Jones etc), SuperMario duvet set.
If I could choose I'd go for one that matches his room...but I am letting him pick. Cos I'm nice Dd and ds are going to have to share soon when dc3 arrives and they are getting new bunkbeds All very exciting.
sorry cant help, I searched high and low during the summer for ds who is into the same things - Sonic, Tom & Jerry or Super Mario sets and found nothing so we went for a dinosaur theme room instead. Then the Next catalogue came out with the cool Sonic one and it doesn't match the room now (havent shown him the catalogue as he'll want it!).
