Turquoise first appeared in "Blue's Birthday," when Steve did some shopping at the present store for Blue. Steve saw Turquoise and bought her after thinking that Blue would like her. It would later turn out that, through a game of Blue's Clues, that Turquoise was what Blue wanted the most for her birthday. She continues to appear throughout the series afterwards.
As seen in "Shy," Turquoise was once shy around the viewers when they got up close to see her. Then, in a flash, she disappeared into her shell. Turquoise poked out of her shell and remembered the viewers at home and the very first time that the viewers and Turquoise met at Blue's birthday party.
Turquoise is a green turtle with a light blue shell that has blue pentagonal spots on it.
In Blue's Clues & You!, she is a lighter shade of green and her spots are shiny.
