Hanglar Sitting on a What?

I admit it, I don't have a clue what this "block" is supposed to be that this adorable Hanglar girl is sitting on. Was it supposed to be a block of ice, or perhaps a cement block, or maybe a birthday present...I really have no idea and if you think you know, I'd be happy if you'd leave me a note! Since I had no clue, I just went ahead and colored it to match the card. Oh well...it's a cutie image regardless of what she's sitting on!  Leave your thoughts...your guess may be as good as one of mine....   Hugs, Gail
