The royal canine unit. I never really known why I like them so much, it could just because I'm a dog fanatic.
All the minibosses, its fun that they are more unique than the actual bosses and have better post battle things to do like the ghost house or mad dummy being just DIO.
Small Shock. It's amazing how just two notes put together make such an emotional, nostalgic effect. Location tracks such as Another Medium, Waterfall, Snowy etc. are pretty underrated as well.
location tracks small bird all that funny extra dialogue
Moldessa. Like, do you even know what it IS? (its a hard mode...moldsmall? forgot its name)
True Pacifist Credits
are
so
underrated
i
love
watching it so much
Also Alphys is so underrated like she's barely noticed by most :(
SHE.ALSO.GETS.SO.MUCH.HATE.FOR.NO.REASON.
I remember searching the credit up and had to finish a 2 hour run through to watch it
Yeah, Alphys gets hated on, probably because she accidentally created the amalgamates, which I think is really unfair. She's definitely in my top 5 Undertale characters and throughout the game I ended up relating to her the most.
