CLOUD SANS!!!
It is a very fluffy cloud, although it is still a lazy skeleton
He is apart from the royal guard (Although he did not want it, he did it thanks to Papyrus) His change of clothes is due to the fact that it is a unique kind of uniform that sets him apart from Snowdin's other monsters
Take care of Snowdin next to Papyrus, although it is usually likely that he will end up sleeping on one of the benches or in the snow; Papyrus constantly scolds him for that lazy attitude
If you're new, he'll be in charge of starting to guide you if he finds you outside the ruins.
He doesn't wear the glasses for aesthetics, Papyrus gave them to him to prevent his 'eyes' from being damaged when he is around.
Here I redesigned its appearance
Darkens when upset (Similar to the second image)
It's the first design I made of it months ago
