Book for a 6 yr old boy

[spottymoo]

I'm looking for a book as part of my nephews christmas present he's 6 1/2 can anyone recommend any good ones that your 6 yr old likes please

DS1 is 5.9 and loves:

Captain Underpants
S.W.I.T.C.H series
Roald Dahl esp. The Twits and George's Marvellous Medicine
Fleabag Monkeyface
Mr Gum

And basically anything with gross/toilet humour :)

thanks for that i've ordered the captain underpants book :)

DS1 likes Horrid Henry, Mr Gum, How To Train Your Dragon and he was getting quite into my old Famous Five books!

DS is 6.5 and loves the Dirty Bertie books - about bogeys and poo among other things. I think they are disgusting and refuse to read them to him so he reads them himself

Other favourites are Dinosaur Cove, Horrid Henry and we've just read Mr Twiddle by Enid Blyton which he found really funny.
