Haley

I dont know if I spelled her name right...
Anyway, her rainbow socks opened my eyes so big!

Here, "big" is not an adverb and you may think "big" is incorrect, but
a famous poet, Walt Whitman uses "so long" in his poem often too, so it's
technically/gramtically wrong but it's still justified to use "so big" in this kind
of sentence Ithink. Iam just saying.
