First, this occurs before [[Buster Spaces Out]], when [[El Boomerang (item)]] is still lost as it is seen in space. In addition, the kids are seen at school with Mr. Ratburn despite spending months off in June and August. Their school could be on an odd system, however--perhaps make up days because of the blizzard. </ref>
