'''Urchin Underpass''' is a battle course that appears as one of the [[new course]]s in ''[[Mario Kart 8 Deluxe]]''. The course is based on the [[inkipedia:Urchin Underpass|stage of the same name]] from [[inkipedia:Splatoon|''Splatoon'']] and contains elements from that game, such as green and purple [[inkipedia:ink|ink]] splotches scattered throughout the course that decrease vehicles' traction. There are also ''[[Mario Kart (series)|Mario Kart]]'' elements, such as [[Dash Panel]]s. There are various paths that all loop around to the main area and several bridges. [[inkipedia:Jellyfish|Jellyfish]] serve as spectators on the course and also appear on the course selection icon.

The music is a variant of the "[[inkipedia:Splattack!|Splattack!]]" theme, which is one of the themes that can play during online battles in ''Splatoon''. When there is one minute left in a match, the music changes to a variant of "[[inkipedia:Now or Never!|Now or Never!]]", which plays in the final minute in Turf War matches in ''Splatoon''. This makes it the third course in the game to have a different music track during the final portion of the match (in this case, when the timer has one minute remaining), after [[Mount Wario]] and [[Big Blue]], which play a different part of the music track during the final segment. The music that plays during the final minute is also the only course music in the ''Mario Kart'' series that does not loop.

Just like in [[DS Waluigi Pinball|Waluigi Pinball]], [[Hyrule Circuit]], and [[Animal Crossing]], this course uses a unique [[Item Box]] roulette sound effect. In this case, it is the ability slot roulette sound from ''Splatoon''.<ref>https://www.youtube.com/watch?v=Jt17vJQx-Lk</ref> This makes it the only battle course in the series to have a unique Item Box roulette sound. In Coin Runners and Renegade Roundup, ''Splatoon''{{'}}s currency, [[cash]], is used in place of [[coin]]s.

==Notes==
*This is the only battle course from the ''Mario Kart'' games to have kanji in its Japanese name.
*This is the only battle course not to feature any spectators from the ''Super Mario'' franchise, as it instead features jellyfish from ''Splatoon''.
*Some background elements appear on the course's walls that are not present in ''Splatoon'', such as graffiti of [[Tanooki Mario]] and an {{wp|exit sign}} featuring a [[Goomba]].
*Despite not appearing in Urchin Underpass in ''Splatoon'', [[inkipedia:Inkopolis Tower|Inkopolis Tower]] appears in the background, replacing a generic skyscraper present in the original game.
*As the original ''Splatoon'' (the only game in the series to feature Urchin Underpass) does not have a Dutch translation, ''Mario Kart 8 Deluxe'' is the only game in which Urchin Underpass is named in Dutch. The Dutch name of the stage was reused for [[inkipedia:Eeltail Alley|Eeltail Alley]] in ''[[inkipedia:Splatoon 3|Splatoon 3]]'', despite the two being completely different stages.
