The Dunes are the third location seen in Undertale Yellow, after the Ruins and Snowdin. They are a large desert region Clover finds themselves in after exiting Snowdin, crashing there after their journey to Hotland goes awry.

The Dunes are located somewhere parallel to Hotland, at points perhaps slightly beyond Hotland. It can be assumed the Dunes lie on the periphery of the Underground, given that the quickest route from Snowdin to New Home is still stated to be through Waterfall and Hotland, much like in the original Undertale, and that Flowey considers the trek through the Dunes to be a detour. The Steamworks is a large structure built on the precipice between eastern Hotland and the northeastern Dunes, connecting both areas. In general, the Dunes seem to be located deeper than Hotland.

The Dunes, much like Hotland, are a scorched and arid region. Unlike Hotland, in which heat comes from an abundance of exposed magma in the area, the Dunes are arid due to a large amount of Swelterstones that can be found there, producing heat and light. A massive Swelterstone also functions as a sort of sun in the area, and can be clearly seen from the mountaintop before the battle with El Bailador.

The Dunes are rich in minerals and other important materials. As such, the East Mines is set up in the Dunes, operated by Mining Co. Besides all the mining activity, the Dunes have two known monster settlements: Oasis Valley located somewhat centrally, and the Wild East, located at the eastern end of the area, close to the Steamworks.

The Dunes were showcased in an animated teaser and the Undertale Yellow launch trailer.

Features

• An area besieged by a sandstorm can be found further forward, reaching the end allows the player to turn off a fan that was causing it.
  • South of the second area with the sandstorm you can find a monster who is a brother of a worker in the mines. They stole their brother's dynamite to open a hole in the wall. Returning here after finishing the mines reveals a hole in the wall where you can find the monster hanging out with some Micro Froggits. Further inside, the golden cactus can be found.
