Teenage Mutant Ninja Turtles (1987 TV series) season 7

The seventh season of Teenage Mutant Ninja Turtles chronologically begins where Episode 142 left off. The Technodrome is still located at the bottom of the Arctic Ocean until the last episode, when it is sent back to Dimension X for the third and final time. However the sideseason takes place during season 4, while the Technodrome is on the Volcanic Asteroid in Dimension X. These episodes were produced before Season 4 and aired in 1993 on the USA Cartoon Express. In Ireland, they aired in 1990 placed between seasons 4 and 5.

The more educational-based nature of the "Vacation in Europe" episodes allowed the use of Christian references. For example, Leonardo da Vinci's painting The Last Supper is seen in "Artless", set in Italy, while "Ring of Fire", set in Portugal, shows a Roman Catholic cathedral, complete with crosses, while crosses in general are avoided in the codes of US children's cartoons otherwise.
