"It's not so serious that we need to use Obliviate!" Wizet said with a smile, waving his hand. "If there's something you want to say, just say it! Don't keep it bottled up inside."
"Fred and George exaggerated a little..." Luna added. "I think they'd be happier if you were willing to say it yourself."
Neville lowered his hands and blinked in confusion. "Why?"
Luna tilted her head slightly, her gaze drifting into the distance. "Like guessing which clump of mistletoe has a Nargle hiding in it..."
"Maybe Professor Lupin and the others would also wonder... whether the ideas Fred and George came up with had already been laid out on the table?"
"Hahahaha!" Luna was clearly not wrong at all. Fred and George immediately burst into laughter.
"Sorry..." Fred and George laughed so hard they doubled over, nearly unable to catch their breath.
It took them quite a while to calm down. Still smiling, they looked at Neville and Hannah. "Neville, Hannah, we hope you're not angry!"
Fred pulled a linen bag from his pocket and stuffed it into Neville's arms without another word. "Take this!"
Neville picked up the linen bag and weighed it curiously in his hand. "What is this? A magical item? Or..."
George puffed out his chest proudly. "This is our Portable Swamp!"
"Just pull it open, then throw it onto the ground!" Fred gestured with both hands, miming the motions of opening and tossing it. "A swamp will appear right in front of you!"
George raised one finger for emphasis. "We spent ages researching it! We only just managed to finish this product!"
"And it's single-use!" Fred hurriedly added. "So remember to choose your location carefully!"
Neville looked even more confused, unable to grasp what Fred and George meant. "Choose the location carefully?"
