Temmie Armor is an armor item sold at the Tem Shop. It is the second most powerful armor in the game, and the most powerful armor available outside of the Genocide Route. This armor is also the only armor not associated with any of the Human SOULs , and the only armor to not have a weapon counterpart. To purchase it, the protagonist must first purchase "tem pay 4 colleg" for G to unlock the item. The protagonist cannot obtain this on a Genocide Route as the option to pay for college is replaced with premium Temmie Flakes. After unlocking the Temmie Armor, Temmie explains that while the armor is amazing, it can and will ruin the experience of combat.

For the track with the same name, see Tem Shop Soundtrack. It is known as the only vendor in the game willing to purchase items from the protagonist. The Tem Shop 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, she dons 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.
