Fumo Fumo Plush Series - I am in antarctica with Cirno what has my life come to

I checked Twitter for other documentation. It feels a little off as all the pictures with Cirno are just in the snow and not with the Antarctic landscape or notable artificial landmarks in the background. However This video has what looks like Antarctica in the reflection of his googles and a blink and miss it frame when he switches from Cirno back to himself. The shadows do still feel odd through.

Didn't know that trees with visible branches were present in parts of Antarctica where the snow and ice are hundreds of feet deep.
