All Zeke and Eppie have to do is play with their new neighbours, Tig and Pop - and take care of them at school, and stay out of trouble for just one day. But if they do all that, their mum will buy them a puppy! Only problem is, Tig and Pop are aliens! So staying out of trouble might not be so easy…This four-book collection includes the whole series of Gretel Killeen’s brain-crackingly funny adventures, with Zeke and Eppie as they get dragged into space, save an ice-cream tree from being stolen and journey to the centre of the stomach!
