Teenage Mutant Ninja Turtles, While there’s been plenty of reboots and movies to this series, the 1987 cartoon version is still the best. About four turtles that mutated into anthropomorphic teens, Leonardo, Donatello, Michelangelo, and Raphael train with their rat ninja master Splinter to take on the evil Shredder and the Foot Clan. It wasn’t the most insightful cartoon, but it had the best theme song, great action, and adventure, and introduced little kids to the word, “Cowabunga.”
