had sent him up in the first place. Becausealthough the fart was no longer howling like a pack of wolves and was now just a tame sputtering, it was still going. And remember that when I say sputtering, thatâs compared to an enormous bang and not compared to one of your farts. Because even if youâve been eating unripe apples and think you just farted the loudest fart anyone has ever farted, it would be considered a gentle breeze compared to the tamest sputtering caused by Doctor Proctorâs Fart Powder. Once Nilly had thought about all this, he swung himself quickly back into the sitting position heâd been in when heâd flown up. And once the seat of his pants, with the open Velcro flap, was pointed straight at the ground, to his relief he immediately started slowing down, thanks to the air pressure of the fart. But he also knew that the fart was going to be over soon and there was still a ways to go until he was back on the ground. Nilly tried as hard as he could to keep it going, because even a twenty-five-foot fall is very high for such asmall boy. And thatâs exactly how high he was above the ground when the fart finally came to an end.
âNILLY!â LISA YELLED.
âNilly!â Doctor Proctor yelled. They were still looking around for him like crazy.
âDo you think the powder exploded him into smithereens?â Lisa asked.
âIf so, the pieces must be so small that we canât see them,â Doctor Proctor said, adjusting his motorcycle glasses and studying the ground where Nilly had been standing when the fart happened. All of the grass was torn up and there was a little pit there.
âWeâre never going to see him again,â Lisa said. âAnd itâs my fault. I shouldâve noticed that he was holding the tablespoon.â
âNo, no. Itâs my fault,â Doctor Proctor said, getting up again. âI should never have tinkered with the formula.â
âNilly!â Lisa yelled.
âNilly!â Doctor Proctor yelled.
âWhatâs all the commotion?â someone complained from over by the fence along the road. âAnd what are you doing here, Lisa? Dinnerâs on the table.â
It was Lisaâs father, the Commandant. He looked gruff.
Doctor Proctor stood up. âMy good sir, the whole situation is hopelessâ,â he started, but was interrupted by a voice barking from behind the fence at Nillyâs house.
âWhatâs all the commotion?â It was Nillyâs mother. She looked mad. âDinnerâs on the table. Has anyone seen Nilly?â
Doctor Proctor turned to face her. âMy good maâam, the whole situation is hopeless. You see, your son, Nilly, he ⦠he â¦â
Then Doctor Proctor was interrupted for the third time, and this time by a high-pitched boyâsvoice that came from above: âHeâs sitting up here wondering whatâs for dinner.â
All four of them looked up. And there, on top of Doctor Proctorâs roof, stood Nilly with his arms crossed, wearing a hockey helmet, knee pads, and leather pants with the bottom flapping around.
âDonât move,â called Professor Proctor, running into the cellar.
âWhat in the world are you doing up there, Nilly?â his mother squealed.
âPlaying hide-and-seek obviously,â Nilly said. âWhatâs for dinner?â
âMeatballs,â Nillyâs mother said to Nilly.
âFish au gratin,â Lisaâs father told Lisa.
âYippee!â said Nilly.
âYippee!â said Lisa.
âYou guys can go back to playing after dinner,â Lisaâs father growled.
âBut not up there,â Nillyâs mother said. âGet down here right now.â
âYes, Mom,â Nilly said.
The professor came running back out of the cellar with a ladder that he immediately leaned up against the wall of his house so that it was resting against the gutter. Nilly crawled
