Izzy and her friends are on a school trip to a big lake. Gary Petrie is excited because the lodges where they’re staying have ROBES AND SLIPPERS! The lake is dark and deep and a bit scary. But it’s when they open their packed lunches that they know! There’s a MONSTER in the lake and it’s coming for their CRISPS!

Laugh-out-loud fun from Blue Peter Award winners Pamela Butchart and Thomas Flintham.
