Bolbe is a lake goddess, and a fresh water one. But is not a ruler like Amphitrite. She is an extremely beautiful lake goddess and is a nymph. She dwells in a lake in Greece called Lake Volvi, Lake Volvi being fresh water. She is a fresh water goddess.
Bolbe's personality strangely does not match her appearance, she is far too perky for anyone to like her, and she wears a hat made of weeds, dead flowers and seaweed.
