Concept arts for Glam Dummy, Sad Dummy, and Noteblook. Glam Glitter-kun's final design is by @paintedhen but the second-to-last picture here was my first idea before Emerson stepped in.
Noteblook (the Dummy from the Ruins in UNDERTALE) has always been a bit tricky because they virtually have no character to them in the game. Since their Check data is a (very bad) poem we came to the conclusion that they liked writing and poetry, but still had a bit of sass to them like their family (they just leave the tutorial if you're too boring for them). Their name comes from notebook + -blook.
Glam Dummy is not a training dummy, but a clothes mannequin! He wields large scissors and commands an army of mini mannequins. Minniquins. In the Mew Mew Kissy Cutie universe, Mew Mew Kissy Cutie's rival is a familiar-looking bishie cat man named Glitter-kun. The last image is the design on Alphys' shirt, meant to invoke the 2010s anime merch you probably have in the back of your closet.
