The Bollabies are small marine magical creatures. They can take the form of any marine life they choose.
Due to the fact that they can take the form of any marine animals it is hard to tell them apart, however they normally resemble regular blue fish. They have big round turquoise body with glowing green light covering it and usually sad-looking face and big, green eyes with giant pupils. When they change form, they pop like bubbles.
The Bollabies were seen in many episodes in Season 5. They are shown to be playful when Nissa played with them in one episode.
The Mystery of the Abyss
