Starting on September 25, 1989, the series was expanded to weekdays and it had 47 more episodes for the new season. There were 28 new syndicated episodes for season 4 and only 13 of those episodes aired in 1990. The "European Vacation" episodes were not seen in the United States until USA Network started showing reruns in late 1993 and the "Awesome Easter" episodes were not seen until 1991. These episodes were delayed because of animation or scheduling problems. On April 21, 1990, a drug-prevention television special was broadcast on ABC, NBC, and CBS named "Cartoon All-Stars to the Rescue" that featured some of the most popular cartoons at the time; representing TMNT was Michelangelo, voiced by Townsend Coleman.
