This is the Littlest Pet Shop Topic! Littlest Pet Shop, also known as LPS, is a discontinued toyline from 2005 made by Hasbro.They are small, cute bobble-head animals that you can play with and collect. There is a large online community, especially on YouTube, going strong to this day. LPS have become rare collectibles because of that they are discontinued. You cannot find LPS in stores right now, but the original Generation 2 pets will come back in 2024 as stated by Basic Fun, who now owns LPS, in their plans for the brand.
Just in case, here's a picture of some LPS.
