S.W.I.T.C.H 5: Crane Fly Crash

Josh and Danny must go on a rescue mission to save their annoying big sister, Jenny, when she accidentally uses the S.W.I.T.C.H spray on herself and turns into a crane fly!
The twins know there's only one thing for it - they'll have to change themselves into crane flies too, and try to keep their sister out of trouble.
However risky . . .
Can the boys resist the lure of the light bulb and stop Jenny from getting legless? And will Piddle the dog be able to resist a crunchy, bugtastic snack?
Petty Potts's diary entry:
Victor Crouch's spies could be anywhere! I keep imagining that old eyebrow-less freak staring through my windows . . .
But I suppose I do have to remember that sometimes I see and hear things which aren't really there. That's all part of the package when you're a genius. I will make sure Josh and Danny keep very watchful, though.
