Littlest Pet Shop began as a Hasbro toy line and became an animated television series in 2012, following Blythe Baxter and the pets at a day camp in Downtown City. Short voice clips from the show spread through fan edits and soundboards because the characters speak in expressive, high pitched voices that work as standalone reactions. This thank you line survived as a wholesome meme option, used when creators want gratitude to sound adorable rather than formal, ironic or over the top.
