Lunch just got dangerous. Josh and Danny don't know it yet but something sinister is waiting in one of their lunchboxes. One taste and the twins will get ears in their kneecaps and a strange ability to chuck up brown goo - just like a grasshopper. But Petty Potts - the mad scientist from next door-wouldn't let that happen - would she?
