Week Siblings

The Week Siblings (Japanese: 曜日兄弟 Weekday Siblings), also known as the Once-a-week Siblings, are seven characters from the Generation II games who will appear at a certain location depending on the day of the week. They were one of the aspects of the game taking advantage of the built-in clock system.

At all times on Route 26, a note in the house of the Week Siblings can be found, saying when and where each should appear. By going to the location on the right day of the week and talking to the Week Sibling, they would give players a certain held item. Each Week Sibling would only give a player one item ever; if someone were to visit them again next week, they would have nothing.
