Applejack usually has her mane and tail tied with one red ribbon each, and her Rainbow Power appearance bears not red but green ribbons. In real horse shows, a ribbon of one of four colors may meaningfully be tied to a horse's tail, a red ribbon meaning the horse is a kicker, and a green one that it is unpredictable.[dubious – discuss]

This is a reference to the phrase "jumping the shark", which refers to the point where a piece of popular culture, usually a TV series, declines in quality and gives in to programming gimmicks so much that it becomes unwatchable.
