Original description from derpi:  
I missed my chance to make my customary christmas derpy last year. That is to say, it was as good as finished but I hadn’t gotten round to painting it. Now I have. Yay!
 
It’s about 7 cm long (2.7 inches) and fits snugly in her glass ball to hang in any christmas tree (maybe next year) but can also be taken out. I had thought about gluing her in there, but now you can put her anywhere and she really can’t fall out anyway.
 
I like it. I like it a lot. I like it so much that I’m thinking of making more (mane 6 maybe?) and not just because I have a bunch more of these glass christmas ornaments.
