Splash Hill Zone Act 3 comes from Sonic the Hedgehog 4 Episode 1, released by Sega in 2010 as a downloadable follow-up to the classic Mega Drive games. Splash Hill Zone is the game's opening tropical stage, and Act 3 is its closing section, so its music was designed to keep the pace high. The soundtrack, associated with composer Jun Senoue, circulated widely through gameplay uploads and soundtrack videos, and fans continue to reuse this track in edits and streams because it instantly signals classic Sonic speed and seaside colour.
