A family in Sakura City is investigating a serious mystery. Their pudding disappears from the fridge, even when names are written on it.

The case began last Sunday. A high school girl wrote her name on a cup of pudding and put it in the fridge. Two hours later, it was gone.

"This is not the first time," she said. "My name was clearly written on it."

Her younger brother said he knew nothing. However, there was caramel on his spoon.

Their father said the situation was difficult. "In our house, pudding is more dangerous than money," he said.

The family made new rules. Everyone must write their name in large letters. They must also take a photo before putting pudding in the fridge.

The mother suggested a safer plan. "Maybe we should buy five puddings," she said.

The next day, the family bought five puddings. By evening, all five were gone.

The younger brother said, "This mystery is getting bigger."

Police were not called.

The family will discuss the problem again after dessert.
