A comprehensive list of my fanmade My Singing Monsters islands in some order and what they aim to accomplish:
Miscellaneous islands
Stupian Badlands - Hubris from mid-2020. the only reason this was brought back was for me to admit that I have made mistakes, and the indefinite hiatus on this island was one of them. Also a way for me to finally reveal that Philerup and Strycniadmin were originally made as Stupians before their current incarnations. Wait i don't think I've ever formally mentioned Philerup's existence.
Crossover Falls - This legally never existed (cover of the Gravity Falls title theme)
Meme Police Station - This also legally never existed (unimportant)
Abandoned Farlands - my dabbling into creating a class of my own (the repurposing of Strycniadmin). Has already been fully composed.
Paragormal Quad islands
Har-V's Pizza Palace - scrapped Paragormal Quad island from before the elements were revealed and I thought it was going to Gormalgamate from Nitebear. And then Digiris's Dimension got released.
Shellphone's Seaside - Paragormal Quad island. Plus Chuckipa because I messed up and needed something for that track.
Invaderraver's Racetrack - Paragormal Quad island, Glass Race from Hamsterball Gold edition.
Eclips' Eclise - this never existed in any finished state. Was composed in 15/4.
Canon Otherworlder Islands
Damaged District - some monsters that sounded good together
Grandfather's Coldroom Island - also some monsters that sounded good together
Stygian Showtime - a selection my favorite monsters in the community, except I decided to animate it. Void Beast Angler is also here for some unexplainable reason. Also contains two [TV TROPES - Suspiciouslly Similar Substitute]s in the two rares that have been designed (Rare TorsynX and Rare Stattick are very clearly Estuary Namaah and Nerdby respectively)
Musical Purgatory - a Gold Island equivalent for Stupian Badlands, Abandoned Farlands, Damaged District, Grandfather's Coldroom Island, and Stygian Showtime (currently unreleased but fully composed)
Other
Island that contains the Sphericool monsters and a few others - an island that contains the Sphericool monsters (Pianime, R'vrs Symbol, HoneyDoo, and Luriel) and a few others (EmoGV [who may or may not be canonically Sphericool], Cooliminar, and Otamaghost) (currently unreleased)
