Just did the Runescape Xmas event, and you get a new snowman emote, and a snowglobe that fills your invent with snow. Snowballs can be thrown at other people or made into snowmen. It was piss easy, here is my dragon snowman. It is so dull, I cba to do it on Holiday Fizz. Also, I made my skiller Fizz Skills, but can't transfer like a starting amount of 200k to it, so no point.
