I always thought that outfit was Undyne's, never had an idea that it was Paps'...

Why do you think it's his?

I'm just curious if I missed something or something.

Also, didn't she dye her hair for the date?

Normally her battle sprite hair is shown white, in which she has red hair.

However her date sprite has black hair, so she must have dyed it, RIGHT???

Only, why would you dye your hair if it's already a beautiful natural red? Why would you dye it black, or whatever color she chose?

Weird fish...

RED IS THE BEST COLOR IN THE WORLD DON'T CHANGE IT TO BLACK!!!
