Tintin and the Lake of Sharks (1991)
One night, in Brussels, Belgium, a pair of crooks discreetly break into the aquarium and steal a priceless pearl. As soon as the security guards on duty see the empty shell, they rush away to raise the alarm. The crooks take advantage of the guards’ absence by putting a fake pearl, the same size as the real one, in the shell. When the guards return with the director and the director sees the fake pearl, he thinks the guards were making it up, but then has second thoughts about the incident as a similar case happened at another museum two weeks before.
