Bubbles

Bubbles brings dreams of fatherhood to humans who are usually on their way to being fathers themselves- such as represented by the seahorse motifs of his mobiles. However, this theme does not end with the dreams he brings to humans, but also carries on to how he treats his fellow Yumes. He, almost seeing it as a responsibility, goes out of his way to look out for others of his kind like a dad would his children. Constantly checking up on everyone, joking around, and overall bring a happy-go -lucky presence everywhere he goes.
He especially likes helping out, physically and emotionally. If a Yume needs help carrying something from one place or another, he is there and jiffy all while carrying a hearty smile and encouraging words. If he passes a Yume feeling glum, you better believe he will drop everything to try his hardest to make them smile- whether it by being making cheesy jokes or asking them to play a game with him.
However, he seems to have a certain smugness, or pride to himself. He is confident in his physical abilities and comfortable in his ability to handle himself- making it so that if anyone does treat him how he usually treats others- it frustrates him. He sees himself as a caretaker, and not someone who needs to be taken care of himself.
Lastly, of course, like any dad- he loves to fish.
