A swirly picture and heavy breathing doesn't make something creepy. But I guess the beeping did it for you?
I think that it's what Giygas -is- that's creepy/horrible - and if you don't know that, then it doesn't really mean anything.
Basically, Giygas is evil itself - once had a physical form, but as it grew more powerful, it lost its shape, and finally its mind. Now it's just a dimension of evil that only exists to destroy everything. Not only that, but the picture lets it down a bit. Giygas is a twisted, red, screaming face, and as you destroy it, it says stuff like...
"It hurts, Ness?"
"?I?m h?a?p?p?y?"
"?friends?"
"Ness, Ness, Ness, Ness, Ness, Ness, Ness, Ness, Ness, Ness, Ness,
Ness, Ness, Ness, Ness, Ness, Ness, Ness, Ness, Ness, Ness, Ness, Ness,
Ness?"
"I feel? g? o? o? d?"
"?I?m so sad?"
Also, the inspiration for Giygas "came from a traumatic childhood experience where he accidentally walked into an adult movie theater and caught a glimpse of a rape scene in the 1957 film "The Military Policeman and the Dismembered Beauty""
So the whole fight is pretty creepy. But if you don't know that, then yeah, it's just slightly odd music and red gas, hehe.
