They are three distinct slime girls. Their bodies are semi-solid and humanoid, albeit made of slime throughout. The three of them can merge and unmerge among themselves at will in any order or combination, being all three or just two of them. The three of them do not always agree with each other as each of them is different. - Dulee: nerdy and shy. She is all green. - Katie: cute and bubbly. She is all pink. - Madison: troublemaker and uninhibited. She is all gray.
