Neville shook his head at Gawain's antics. "Here," he said, offering the last of his and Nimue's ice cream to Luna. "I need a free hand, and Nimue's going to help by picking the lucky duck, aren't you, Petal."
"Duck," Nimue agreed, the D hard enough for Neville to wonder if she was showing off to her brother. "Which one?" he asked her, and tried sighting along the line of her excitedly waving hand.
He paid the stall holder the fee, and then raised his wand. While he could simply have summoned his quarry, it was an unwritten Wizarding law that the rubber ducky game required more inventiveness. Accepting Nimue's encouraging pats on his chest and shoulder, he aimed his wand and tried a water spout charm that would lift the duck out of the track. Unfortunately, the result of his spell wasn't the intended one and the duck he had been aiming for exploded in an impressive pop of yellow rubber.
Nimue uttered a disappointed, "Dada...", and the stall holder laughed: "I've never 'ad such a day for keeping back prizes. Though... it's gonna cost a bob or two ter replace all the ones I've lost."
Neville carefully tucked his wand away, not wanting to do any more damage. "It's all down to Mummy now," he informed the twins.
