The one with Gaster's face is Gaster haha

The one with the snowflake is Snowy (Snowdrake)? Could also be Sans

The ones that are purple with white stars are Toriel

The one with pink, blue, and yellow stripes is Frisk, so is the lacy pink & blue one at the bottom

The one that's green, yellow, white (unless that's shine), and red is (Omega/Photoshop) Flowey?

The ones that are orange with a yellow stripe are Papyrus, so is the orange one with yellow stripes and white stars

The one with the purple & yellow lace is Asgore

The one that's blue with white snow particles is Sans

The one that's blue with red stripes and yellow stars is Undyne

I think the rest are either OCs or backround characters I forgot.



EDIT: The one that's pink with blue & white hearts is Mettaton, I forgot he had blue on him

EDIT 2: The one that's pink with white stripes could also be Mettaton
