Undertale

N.B. The subject of this article is not something created by Andrew Hussie. However, it is
considered relevant to the Wiki's scope due to connections it has to one or more of his works.

Undertale is an RPG created by Toby Fox. It was released on September 15, 2015, and quickly gained widespread acclaim. An episodic spinoff game, Deltarune, released its first episode in October 2018, and then released its second episode in September 2021.

Toby Fox apparently started developing Undertale in Andrew Hussie's basement.

Connections with MSPA

Allusions

As Toby Fox was part of the Homestuck music team, several things in Undertale can be seen as references to Homestuck:

• In the Kickstarter for the game, the top reward tier was "Your fantroll will become canon in UnderTale." This is a direct reference to the Homestuck Adventure Game Kickstarter reward.
• Aaron – an extremely buff partially equine creature who sweats and flexes – may be a reference to Equius and his lusus, especially regarding the unique interaction with the somewhat catlike Temmie.
• Pyrope – a portmanteau of pyro (fire) and rope – may be a reference to Terezi Pyrope and/or Neophyte Redglare, due to their associations with ropes in the context of hangings.
• One of the monsters from Hard Mode, Migospel, bears a resemblance to Gamzee Makara, due to associations with religion and clowns, as well as similar honking.
• A manticore in the lobby of MTT Resort bears a vague resemblance to Jade Harley.
• The Hotland area is highly reminiscent of the Land of Heat and Clockwork, while the Waterfall area is similar to both Land of Wind and Shade. Following this, the Ruins has a similar appearance to Derse.
• Asriel Dreemurr is described as the God of Hyperdeath.

Musical connections

• "sans." was originally a track named "muscle", composed for a Homestuck-related project.
• "Another Medium" is derived from "Patient", an unfinished remix of "Doctor". The same motif also appears in "Waterfall", "CORE", and "Death by Glamour".
• Undertale's Battle Against A True Hero track also is quite similar to Versus ♫ from Homestuck Volume 5, both composed by Toby "Radiation" Fox.
• "Oh My..." is very similar to the opening chords of "Killed by BR8K Spider!!!!!!!!".
• "MEGALOVANIA" appears in the game, although this is not strictly a Homestuck reference, as "Megalovania" is Toby's "signature" song and has been used in a previous project.
• "It's Raining Somewhere Else" seems to be derived from a section in White ♫ from Homestuck Vol. 5.
• "Your Best Nightmare" (3:12 to 3:27) is similar to Terezi's Theme ♫ from 0:00 to 1:07. This is even more interesting because the SOUL linked to that part of your best nightmare is Justice, and Terezi has many ties to justice herself with her sign even being Libra.

Common sound effects

• "Dogsong" uses Mario Paint Composer sound effects. These sound effects have been heavily used in Homestuck, particularly for music relating to Nepeta, and also in the Trickster arc.
• Flowey's laugh is the same sound clip used for trickster and menacing cherub laughter in Homestuck, for example as heard in The Lordling ♫.
• Sans's whoopee cushion sound clip is the same as that used before Caliborn's piano performance.
• The sound effect when killing a monster in Undertale is the same from Openbound Part Two when Mituna crashes into the ground after doing a (not so) sick grind.

References to Undertale in MSPA

• In the Paradox Space comic "Vrisky Business", Vriska Serket asks Equius for a cup of spiders. This may be a reference to Muffet.
• At one point in [S] Collide, Davepetasprite^2 engages in an Undertale-format fight with Lord English.
• Hiveswap: Act 1's OST on Bandcamp contains the bonus track B-SIDE: SPOOKTUNE ♫ by Toby. It's a remix of Relatively Visible Darkness ♫ with the leitmotif changed to that of Undertale's Spooktune. It also contains the track Bedroom for an Annoying Dog ♫, which plays in the basement of Half-Harley Manor; the title is an allusion to the fact that Toby (whose in-game avatar is the Annoying Dog) started to develop Undertale in Hussie's basement.
• Half-Harley Manor ♫ and A More Defensible Position ♫ contain Snowdin Town leitmotif.
• Page 211 of Homestuck^2 lists anyngdogkind as a selectable kind abstrata.

Deltarune

Deltarune is an episodic Undertale spinoff whose release began on October 31, 2018. As with its predecessor, it contains many probably non-coincidental connections to Homestuck:

• Chapter 1 shares Homestuck's prominent chess and playing card imagery.
• When the playing card character Lancer threatens to turn the protagonists "into blood", he produces a bucket with a spade symbol on it to catch it;^[image?] the significance of such an object is unlikely to be lost on any Homestuck reader.
• Alphys's square glasses are inspired by John Egbert, as much as "[n]o one needed to know that."
• In Chapter 2, Queen bakes bright green pies.
• Spamton is a red-cheeked ventriloquist's dummy who ascends to a reality-bending cybernetic form.

Musical connections

• "Smart Race" (0:00 to 0:10) resembles The Grubbels' song Broom Temperature ♫ (0:14 to 0:19).
• "BIG SHOT" (0:00 to 0:13, 0:27 to 0:40) is similar to Beatdown ♫ (0:06 to 0:20).
