Wow finally got there last night having worked out that once the snowman melts the hat which you do not have a spare hook for goes on ......

(that would be telling).
Suffice to say that yes the bucket filling and emptying is a major clue, and dont be afraid to drop and rearrange all the hangers, and what's on them. The final thing of the head is a real pain in the backside cos it's sooo heavy it throws everything out. You do get a nice round of applause at the end though
Happy to Help (hinder!)
