In the Republic of Ireland, the series was initially known as "Teenage Mutant Ninja Turtles" just like the US version and the intro sequence was unedited when it debuted on RTÉ Two as part of the Irish tv strand The Den with the airing of the second season in September 1990. After the first two episodes were broadcast, the name was changed to the Hero Turtles version and the intro was edited, except for season one. Scenes with Mikey’s nunchucks and the word ‘ninja’ were always edited out in the actual episodes, though. Episodes were also cut a bit midway through at the point where there would be a commercial break, perhaps because there were no ad breaks during shows on The Den. The show was very popular in Ireland and aired a lot on weekday afternoons on RTÉ in the mid 90s with season 1 being placed between 3 and 4. The European Vacation eps first aired in Ireland in December 1990. In 2007–2008, episodes were aired in their original US unedited form.
