Every Potter and Granger-Weasley kid loved chocolate frogs. It was in their DNA...
"Daddy." Lily wined. "I want toclate fogs."
Harry and Ron had taken the kids on an outing. Ginny and Hermione were both at work.
"No fair." James said crossly. "Me too."
"Fogs?" Hugo asked, eyes wide.
Ron groaned. "Fine."
They went to the store and got loads.
"Daddy, did you know you have a face?" Rose asked.
"Huh?"
Rose held up her Chocolate Frog card for him to see.
Harry quickly took it away. "Rose, honey, these arn't for you."
"Okie-dokie, Uncle Harry."
"I wanna read it." James said. "'Rondald Wezzy helped kill Lobe Villymort-'"
"James-" Harry warned.
"Ok." James pouted.
