Out of the water, she most often appears as a female humanoid with a volume of 90 liters comprised entirely of water. When she enters a body of water, she becomes indistinguishable from her surroundings. She must periodically return to a body of water in order to maintain her volume due to evaporation. She's kind, curious, a little mistrusting of guys, and she unfortunately can't talk, due to being made of water. In the SCP, her cell has what looks like a regular fountain, where she lives in.
