Here are two new characters I've came up with, they are bunny siblings both working as lifeguards at the pool.

Barley is able to turn living things into inflatables (swimrings, ect) with her horn on her head. She can turn herself into an inflatable too but would rather be enjoying herself floating on one. She can be lazy at times and keeps mostly to herself but she does her job effectively.

Lime is able to summon balloons out of nowhere by blowing into his whistle. The whistle doesn't actually have any power, instead it is from the horn on his head. He prefers to stay in his balloony form most of the time. Lime is outgoing and joyful, he likes to summon balloons for the pool guests as well.
