Bubbles

Bubbles is the best friend and loyal companion of Buoy. They found each other at a gathering for non-humans and have stuck together ever since. Bubbles introduced herself by accidentally spilling a drink on Buoy while running from an alien cat-like creature. When Buoy caught her and held her safely out of the alien cat's reach instead of getting mad, Bubbles knew she wanted to be friends. The two can communicate just fine using a series of chirps and chatters (Bubbles' language).

Bubbles has been a wanderer for most of her life, keeping various children company, but they inevitably grew too old for their little friend, whom they thought was imaginary. Only after the emergence of more sentient species did they realize Bubbles had been a real being. She in't resentful though, and understands that they meant no harm. She's sweet to everyone she encounters and wouldn't harm a fly.
