During the night, the temperature dropped to 25 degrees Fahrenheit. Because of this, Drip's state of matter changed from a gas to a solid, so she went through deposition and was frost on the lawn in the morning.
The next day, it started to snow so Drip stayed in solid form for a very long time.
Much much later in drip's life, she became an ice cube in a freezer because she melted from the snow in the spring, then she became filtered water, then was frozen into an ice cube. The ice cube she was in however was left in the freezer for a very long time, so she sublimated from a solid to a gas into the atmosphere.
