How do you get past the screen with the abominable snowman? It looks like the upper right is a door to be opened, just like a few places earlier in the level. I got up to it, (using the cracky-jumpy-bubble thing at the lower right) but I can’t figure out how to open it, since I don’t see any more of those white buttons. Also, can you kill the snowman? I killed the robot dog, but emptied all my snowballs onto the snowman to effect. Perhaps you have to kill the snowman in order to get further in the level?
