The Tem Shop is a vendor found in Temmie Village, which is hidden in Waterfall. It is known as the only vendor in the game willing to purchase items from the protagonist.

The Temmie Shopkeeper has the same basic appearance as all other Temmies in-game, with a few exceptions: light gray instead of black hair as well as a different hairstyle, and a sky blue and yellow striped shirt instead of a solid Pacific Blue shirt. When the Temmie Shopkeeper is paid to go to college, they don a black graduation cap.

The Shop itself shelves a branch with a leaf, a bone, a glowing purple potion and two single socks, both very different in size and design. On top of a couple of what seems to be cardboard boxes, a picture of the Annoying Dog can be seen. Although these items are displayed for purchase, they are unobtainable in the real game and serve no purpose rather than decoration. The shop's "counter" is also just a cardboard box with the words "TEM SHOP" on its side facing the protagonist, matching the colors and clothes of the Tem Shop owner.
