No, it only has two parts. Try to make the bottom big and the head a bit smaller. To get
it over the bridge, make sure it's already sort of big. This way if you go into the dirt
it won't break immediately. You don't have to catch the bugs, but to get them of the
snowball just bump it. I hope this helps!

Somehow when i made the snowman two days later it disappeared

Well you have to get them to the size where they cant get any bigger. They are about as
big as you when you roll it to it's limit.

Then you should try to push them over the bridge if not then roll them together.
(perfect snowman): to make a perfect snowman, you will need to make the bottom one to it's
limit, and the top to a little smaller than the bottom! )

Hope i helped! ^^
