Actually I have very good news for you Jolly, our very own Teacher Tim did an advanced audio blog http://www.koreanclass101.com/2010/10/2 ... ree-bears/ on this very subject. Also if you do a youtube search you will find several versions of the song - some with the lyrics so you can follow along.
Anyway, it is very nice to see you here at Koreanclass101 - please don't be a stranger - come often - ask as many questions as you like or just come and share whatever is your Korean interest.
Yes right! There is a audio lesson of this 3 bears song like George mentioned.
Tim used 히쭉히쭉, though.
Sometimes, We sing this song with 으쓱으쓱.
I think you heard "으쓱으쓱" which is a mimetic word.
The meaning is "motion of lifting the shoulder up and down". Imagine when a baby is acting cute like a dance they learn from school.
