Trivia

• The Japanese titles of A CYBER'S WORLD?, WELCOME TO THE CITY, Lost Girl, Giga Size, and Knock You Down !! are written in English.
• The Fangamer vinyl of the DELTARUNE Chapter 2 OST contains Dance of Dog as the 48th track, extended to 2:03 on side D. The track originates from Undertale's Dog Check.
• The track Determination from Undertale is reused for a gag scene in which the Annoying Dog runs over Kris with a toy car. This song is not included on the DELTARUNE Chapter 2 OST, and is internally referred to as gameover_short.
