저만치, 흘끔, 빙긋
I am reading a children's book and I found this sentence which I am trying to translate '바로 저만치 소달구지 바퀴 자국에서 뒹굴고 있던 흙덩이가 곁눈질로 흘끔 쳐다보도 빙긋 웃었어요'.
I can't seem to find the exact meaning of these words in the dictionary : 저만치, 흘끔, 빙긋.
What are 흘끔 and 빙긋 as parts of the sentence? Can they stand for themselves in a sentence(or are they adverbs or something)?
