When Haroon's mum brings his baby brother into school, Izzy and her friends are ALARMED! The baby is clearly using mind control because the office ladies are being REALLY NICE. He spells space words with his blocks and he REALLY LIKES SCHOOL DINNERS! But it's when he starts USING HIS ALIEN PHONE that they know. Haroon's baby brother is from outer space and he's MAKING CONTACT WITH ALIENS! A brand new laugh-out-loud story created especially for World Book Day by Blue Peter Award winners Pamela Butchart and Thomas Flintham.
