innocent fluffy face and narrowed his blue eyes accusinglyââtrying to bite my legs off!â
Piddle whined guiltily.
âPoint made!â Josh said.
âBut donât you see? Yesâthe main problem with being S.W.I.T.C.H.ed is the nearly getting eaten!â Danny said. âBut
nothing
eats an alligator, does it? NOTHING!â
âYouâre right,â came a voice from the other side of the fence. They both jumped, and Josh could see the top of Petty Pottsâs tweedy old hat,while Danny could make out one of her eyes behind its thick glass spectacle lens, peering through a knothole in the wood. âNOTHING eats an alligator,â went on Petty. âDonât you two think itâs time you came back to my lab? REPTOSWITCH is waiting.â
There was a long silence in the garden, broken only by a soft whimper from Piddle. He was scared of Petty. With good reason. He got up and ran back into the house.
âCome on,â went on Petty. âWeâre all in this together now. You are part of the S.W.I.T.C.H. Project. If you hadnât found all my missing REPTOSWITCH cubes with the secret code in them, I never would have gotten past insects, beetles, and arachnids. Weâve already done amphibiansâand now REPTOSWITCH is perfected! Itâs what youâve been waiting for all summer! Itâs finished. It works! Itâs time to have your reward and try it out!â
Still Josh and Danny said nothing. Petty Potts was amazing. But dangerous. She really couldnât be trusted.
âVery well,â sighed Petty. âI wouldnât dream of
making
you try it. Letâs just forget it. Iâll go back to my lab.â Her voice took on a tragic tone. âAnd go on with the S.W.I.T.C.H. Project alone. Donât you worry your little heads about me ever again. Maybe Iâll see you at the post office someday . . . Goodbye.â Petty waded across her garden, waist deep in weeds, and went into her shed. Through the door at the back. Down the secret passageway. And into her underground lab.
Danny joined Josh on the top of the jungle gym, and for a long time they stared across the fence. Danny ran his fingers through his messy blond hair and frowned. âWe
want
to be alligators!â he whimpered. âWhy arenât we jumping over the fence?â
âBecause,â Josh said, scratching his own much shorter, neater blond hair. âWhenever Petty asks us into her lab, itâs like a spider inviting us into its web.â
âSo. We donât go,â Danny said, a few seconds later. âWe just . . . forget about it all.â
âThat would be the sensible thing,â Josh said.
They stared over the fence some more.
âLetâs go, then,â Danny said.
They were in Pettyâs lab fifty-seven seconds later.
âWe start gently,â Petty said. âYouâve never been a reptile before, and it may be a bit of a shock.â
Danny snorted. âWhatâlike being turned into a spider wasnât a bit of a shock?â
âOh, do stop harping on about that,â snapped Petty, shaking a small plastic spray bottle in each hand. âYou know the first time was an accident. I never intended to involve two nosy boys from next door in any of my work. If you and your dog hadnât trespassed in my lab it never would have happened at all.â She beamed at them, and her gray eyes glittered behind her glasses. âAnd wouldnât that be a shame?â
âWhat kind of S.W.I.T.C.H. is in the bottles?â Josh asked, mesmerized by the green liquid sloshing around inside them.
âItâs lizard,â Petty said. âTwo different native types. Like I said, we start gently.â
âLizard?â breathed Josh, awestruck. He adored lizards. He liked to creep up on them while they were basking in the sun and watch them for ages until they moved away like quicksilver into the
