Soon the boys have wings, 360 degree vision, and a strange attraction to dog poo. Flying into enemy territory is a dangerous business. It's definitely snot funny when they encounter a hairy nostril but that's nothing compared to a sticky web and the power of the swat. Will they make it a flying a finish and save the day, or will the twins be turned into fly soup? Petty Potts's diary entry: Josh is the cleverest one and really knows his wildlife, so he should be quite a help in making notes. Danny is bright too, though, and very brave considering he is actually quite scared of bugs and insects. Of course, most importantly they are four extra eyes in the search for the missing REPTOSWITCH cubes ...if Josh and Danny can help me find them, I will be able to advance the project to the reptilian level!
