Bunji has bought a Sarracenia, a carnivorous plant.  Trying to catch live insects for food, he places a trap in the house and runs around with an insect net, but it doesn't quite work out.  Dad has brought Bunji and Fumi to the park. While he keeps an eye on the children as they play freely, he suddenly notices that he's being eyed with suspicion by the other moms. The heater has broken down and Mom can't work because her hand is too cold.  A hot water bottle that she found in the closet was taken by Grandma. Along with Bunji and Fumi, they try various tricks, but they can't shake the cold... Fumi is writing what she wants for a christmas present to Santa Claus.  She obsessively lists what she wants, but...
Ah, that's right.
