Conan had known that the Shounen Tanteidan deciding to cook something would end badly, but Haibara didn't stop them, so he hadn't bothered to try. They'd said they were trying to bake a cake, but he still has no idea how they managed to cause this catastrophe. Thankfully, the oven hadn't been touched—he'd made sure to tell them that Agasa-hakase would be the one to put the cake in and they'd agreed to that much—but the entire kitchen has been transformed into some kind of disaster zone. There's flour and eggs and batter everywhere—even on the ceiling!
A/N: Prompt word: catastrophe- utter failure; fiasco
