His dad bounded into the kitchen, having just arrived home from work, seemingly more excited than anyone who had just finished a full shift had any right to be.
"Dad?" he asked, somewhat wearily, watching his dad place a small peck on his mother's lips and another on the baby's head.
"Charlie! Brilliant!" His dad rounded on him with a manically excited grin. "Get your brothers, I've got something to show you all!"
"What is it?" his mum asked, at the same time as he yelled:
"Guys! Get in here!" He could hear complaints from the adjoining room, but his brothers seemed to be on their way - slowly, perhaps, but it was really the best he could have hoped for.
"Well, I could have done that," his dad said with a frown, momentarily deflating.
"Why didn't you, then?"
"Charlie," his mum's warning tone put an abrupt end to that line of conversation.
"What d'you want?" Percy asked, scowling around the kitchen.
"Dad says-"
"Look," Arthur interrupted his second-eldest loudly, pulling an object out from the folds of his robes and setting it down in the centre of the table, the bright yellow standing out even in the organised chaos of the Weasley's kitchen.
All six boys stared at the thing in silence, even the youngest two quieted in the face of this extraordinary object.
"What is it?" his mum asked again, staring unimpressed.
"It's a rubber duck," Arthur whispered, still not turning from the object.
"What does it do, Dad?" Bill asked.
"I have no idea."
