Traboulidon was a French language children's television show made in Quebec in the mid-1980s. Its stories revolved around the adventures of Philo and Bulle.
Due to an accident, they were both trapped in a computer game of Philo's invention, and in every episode had to beat a "level" to try to advance further and finally be able to leave.
Among various recurring characters, one would appear as different bad guys of the week but always having a name containing "nespa". Although they of course always recognised him, he never did or at least never acknowledged he knew them.
