Carmen Sandiego Wiki

Episode 28 is the twenty-eighth episode of the first season of Where in Time is Carmen Sandiego?


Dr. Belljar steals Leeuwenhoek's microscope from the Netherlands in 1674.

After a Data Boost at the time of the crime, the time pilots receive a message from Millennia, who reminisces how Edward Jenner invented vaccination in the 1790s. Once the time pilots get there, however, Belljar zaps their 'fact fuel.'

Following another Data Boost, the time pilots meet up with a fruit vendor who explains that English scientist Alexander Fleming has discovered penicillin, which leads the time pilots to Illinois in the year 1941. When they reach their destination, they do Global Pursuit in the early 1940s.

After receiving clues from Dr. Belljar's taunts, the time pilots travel to 1990, when the Human Genome project was begun, and retrieve the microscope.

Francis captures Dr. Belljar but missed the last question allowing Carmen to escape.
