ok ok have more Undersail
Alphys is an axolotl, Blooky is a jellyfish ghost, Shyren is an anglerfish (or even more of an anglerfish than she is?) and Mettaton is a bathyscaphe, idk
also i kinda fused two headcanons about MTT’s heart container, so it still looks like a belt but is also an aquarium sorta thingy
(btw i’m sorry if i suck at the resemblance, i’m no marine biologist and i’m certainly not googling anglerfish photos hhh)
honestly just really like undertale
