Good morning everyone, it's June 21st 2019 and I hope you're having a fine day.  Toxic Caves is the 12th and semifinal zone of Sonic Hysteria.  Eggman expanded it from its original small size into a massive undersea tunnel connecting all the islands.  He also armed it with tons of security, so you're not gonna have a smooth time making it to the end.

Toxic Caves Act 1 - Sonic Hysteria OST

The variation of Quartz Quadrant Bad Future that plays when you run outside.  Really makes you take in that view and see how bad things got here.

Quartz Quadrant Present (Outside) - Sonic Hysteria OST

"I think this is the most finished-sounding of all the unused tracks. I made this before I really knew Undyne’s personality, so while the arrangement is good, I felt like it didn’t sound enough like being heroically punched in the face."

(Unused Track) - UNDERTALE - Undyne Battle

U GOT ME ⚡️

was a little battle against time to get this done before my travels, didn’t want to ruin the momentum i’ve been feeling !

this one is somewhat a little darker in vibe, slight switch up from the super melodic stuff - still kuspe tho, hope you likeyy

Kuspe - U Got Me

Blown-out energy and clenched-jaw bounce. Black Static rides a chopped, metallic melody with a punch-first 808, clipped transients, and hats that drill straight through the mix. Think Yeat urgency with an X-style snarl—minimal harmony, maximum impact. 140 BPM • D# minor (E♭m).

Track facts

Tempo/Key: 140 BPM • D# minor / E♭m (Camelot 2A)

Palette: chopped synth/guitar timbre, bell accents, occasional timpani/impact hits, saturated 808/sub, tight hats, cracking snare, short room/plate verbs

Structure: 8-bar intro → 16-bar hook → 16-bar verse → alt hook → outro

Black Static (140 BPM D# Minor)

City in 16-Bit feels like walking neon streets inside an old arcade screen — retro synth bells flicker, drum machines tick, and a bassline bounces with pixelated warmth. At 100 BPM in C minor, it rides the sweet spot between nostalgia and drive: dreamy pads blur into magical arp hits, while gated snares push the rhythm like a side-scrolling skyline. Melancholy but alive, it’s a synth-pop postcard from the 80s–90s future — equal parts arcade romance and midnight city glow.

City in 16-Bit

The Lagoon drifts in warm and nocturnal — hand-percussion and shakers sketch a tide while muted guitar and marimba/kalimba plucks ripple on top. A rubbery sub and rounded kick keep it deep; airy vocal ad-libs glow like lights along the waterline. At 120 BPM in B minor, it’s smooth, hypnotic, and radio-ready: a clean first drop, a breezy mid-break with call-and-response leads, then a fuller second chorus that lifts without crowding the mix. Sunset energy, midnight groove — Afro house built to sail.

The Lagoon

After getting separated in Hill Top, one of the heroes arrives at Festival Night a bit late to the party.  They'll have to take the backstage route to meet up with everyone else, who are currently on the main stage dealing with some shenanigans.

Festival Night Act X - Sonic Hysteria

Inside the once-glistening caves of Quartz Quadrant.  Now a burning, mechanized wasteland.  When running in and outside the stage, the music fades seamlessly into the other variation.
