|This article is about D.W.'s snowball. You may be looking for Bally, Bud's snowball or Snowball (character), the character version of this item.|
After the blizzard, D.W. and her family play outside in the snow. D.W. described it as the "best day ever", so she decided that she needed something to remember it by. Mrs. Read places the snowball on a plate and puts it in the freezer. D.W. is very attached to the snowball and cares for it through the summer, but then all of a sudden the snowball disappears. She constantly accuses her brother Arthur as the snowball thief, especially whenever D.W. (or, in one instance, Francine) needs an excuse to make Arthur look bad or try to force a confession from him; he maintains that he has no idea what happened to it.
Nobody actually knows what happened to the snowball. There have been several theories as to its disappearance, but it has been strongly indicated on at least two instances that it was in fact stolen by aliens (whether this is a merely a throwaway joke or not is unclear). At the end of "D.W.'s Snow Mystery", aliens are in their spaceship sampling the snowball (thinking that it's human food), and one of them says, "I told you they would never figure it out". At the end of "Return of the Snowball", two completely different aliens, both adolescents are indicated to have stolen the snowball much to the dismay of their father. These two completely different depictions of this alleged explanation may be further indication that the alien explanation is in fact a joke, further deepening the mystery behind the snowball's disappearance.
Furthermore, in "Through the Looking Glasses", Arthur throws away a snowball-shaped object into a trash can, which D.W. proceeds to take out and look at. It is unknown if this is her snowball, or if it is another fabrication of Arthur's intended to end D.W.'s constant nagging.
