Greg James joins CBBC Book Club to celebrate Roald Dahl, sharing his favourite books and fun facts about the legendary author. Greg picks Matilda as his top choice, but gives a heartfelt shout-out to James and the Giant Peach as an underrated gem of 'simple silly ideas that just works beautifully.' Kids share their own Roald Dahl reviews and cosplay, while the team debates a fun 'would you rather' challenge: pull endless pranks like the Twits, or execute one perfect practical joke like Lavender in Matilda?
