They were coming alive! ITS ALIVE! But what to make them do? That was a good question, in all honesty she was set on an army as what do you call a large group of snow people? Although she didn't get that many done in the end so there was that aspect, and she was feeling pretty cold now for once. So she didn't have it too much in her to continue building more and creating a snowy re-enactment of the battle of hogwarts.
What they could do though, and add a nice sight for anyone going through, and herself for today. She knew a spell for making things move but she's not done great with it, preferring more practical, like making herself be able to dress with magic, although so far she could make them fly on, appearing on always was a little tight. Its just easier without magic she figures.
"We could make them dance, be a nice sight and be good until the sun comes out...if it ever comes out." Sun was rare in England, let alone Scotland where snow is an actual thing that happens...occasionally. But regardless, it would be a nice sight.
