Hilarious, illustrated school-based antics where everything that happens leads to drama and running around and even some fainting! 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!
