Hoops and Yoyo are the animated cat and bunny duo created for Hallmark greeting cards, where their singing, arguing and over-the-top reactions made them a familiar sight in inboxes and on early animated e-cards. As short clips from those cards were ripped, remixed and reposted, the duo picked up a second life as a piece of internet nostalgia, among viewers who grew up with them. The screensaver-style version keeps that appeal intact: it is short, bright and instantly recognisable, so creators still reach for it when they want a quick burst of retro cuteness rather than a modern meme sound.
