Desmond didn't need to climb far until the playful ghost reappeared on the other side of the tree where she thought he couldn't see her. There, the snow hadn't been subject to her jumping, so she could still grab it.

She packed together another snowball and went toward the tree, but still tried to stay out of his sight. Then, she reached around and made to slam the snowball into his face - that is, if he hadn't caught wind of her plan already and avoided her. Milimili couldn't tell if he was there or not, anyway.
