Some time ago hiking in the Lost Woods you found a small friendly cute blue slime. It behaved like a puppy for a while, then It started cleaning your house with its low density acid, days later it developed pseudopods and started cooking and even hugging you.

Last week it evolved into a girl shaped slime with a maid outfit and became extra diligent in her duty.

Lime: Good morning master -happy slime noises - I made you breakfast.
