While catgirl is moving, ghost cannot be seen. They will only become visible again after catgirl stops moving for a few seconds.
If shot by a blood bullet, ghost will be unhurt and turn crimson. While bloodied, ghosts will dash from wall-to-wall like catgirl, but they can only move when catgirl isn't moving.

Ghost smells like freshly toasted bagels. Blueberry and sesame.
