The Magic School Bus Lost in the Solar System their moons (Io for Jupiter, Mimas for Saturn, Miranda for Uranus and Triton for Neptune.) Once on a planet, the user can exit the bus, where a strange satellite called the "whatsit" must be clicked on to bring up an arcade-styled game in which the user, controlling one of the students, must collect one of Ms. Frizzle's tokens (giant coins with Ms. Frizzle's face on them) which provide the user with a clue as to the Friz's whereabouts and activate the "Friz-finder." There are only three clues available, but tokens will still need to be collected to activate the "Friz-finder"
Titania (moon) exists, it would have to be far thinner than that of Triton or Pluto. This upper limit is still several times higher than the maximum possible surface pressure of the carbon dioxide, meaning that the measurements place essentially no constraints on parameters of the atmosphere. The peculiar geometry of the Uranian system causes the moons' poles to receive more solar energy than their equatorial regions. Because the vapor pressure of CO is a steep function of temperature, this may lead to the accumulation of carbon dioxide in the low-latitude regions of Titania, where it can stably exist on high albedo
