The "Tales from the Cosmos" comics are a reference to "Tales from the Crypt", a cult classic horror comic series which began its publication in 1950 and met its demise after the imposition of the Comics Code Authority in 1954.
On Michelangelo's bedroom wall there is a poster for a horror film "the muck man." Muckman was actually a character in the original TMNT toy line and would eventually appear in the original Teenage Mutant Ninja Turtles (1987) series in the episode Muckman Messes Up (1991).
