Microsoft Bob (game included)

Expansions

In addition to full sets of questions pertaining to countries by continent, capital cities, US states, Canadian provinces, bodies of water, the solar system, American and world landmarks, and flags and greetings of the world, sampler question sets were offered in-game for expansion packs on the subjects of Animals: Predator, Pal, or Parasite and Science: Volcanic Landscape. In the BOB user manual these are revealed as specific subsets of what were marketed as add-on packs (a steal at only $24.95 US!), but which were presumably (given the BOB-independent release of GeoSafari: Animals) spun into stand-alone products following BOB's dead-on-arrival launch.

Yes, GeoSafari was distributed exclusively as a pack-in with Microsoft BOB, the only known game for that operating environment.
