Season 1, Episode 4 - "The Secret of the Unicorn (2)"
8 November, 1992
The story begins when a fetish which originally belonged to a tribe of South American Indians is stolen from the Museum of Ethnography in the town where Tintin lives. The following day it is back in the museum, along with a note apologizing for the inconvenience caused, saying that the reason had been a bet. Tintin, who is among the reporters looking into the story, realizes that the replacement is a fake, the distinction being an ear broken on the original but intact on the replacement.
