Olympia's Random Slide
This...is the missing piece of the puzzle.
Measurement: using a calendar
- This episode is Oona's first appearance
- Olympia and Otis meet Oona for the first time.
- The episode's title is based on the classic 1985 movie Back to the Future.
- Oscar keeps snowballs in the freezer when it's not winter, and keeps leaves in a refrigerator when it's not fall.
- The Time Sharks replaced the Time Sheep.
- Olympia, Otis, Oscar, and Oona are zapped into the future on April 1st.
- If the future Olympia, Otis, Oscar, and Oona see their past selves, many things could go wrong (Timetastrophe).
