Overview: Kak Ros and Opah are busy making ketupat and Upin and Ipin offer to help them. They try to weave ketupat but fail. Instead of making traditionally-shaped ketupats, they make unique and weird shapes. Kak Ros scolds them for not being serious about helping her and Opah. Upin finally made a proper ketupat, but the size was too small. When Kak Ros asks him to redo it, they both give up. What will Kak Ros do?
