Star is one of the baby freshwater turtles that appeared in "Pups and the Trouble with Turtles". She was given the name "Star" because her shell pattern resembled a star; also breaking tradition of naming turtles with names that rhymed with "turtle" for the second time (the first being when Marshall named one Joey). Star was named by Skye. She is a member of Alex’s mini patrol.
Since Star is a turtle, she doesn’t talk or do much, beside walk, eat, and sleep. However, the pups still enjoy her company.
Star looks like almost every other turtle in the series, but her shell pattern has a star on it: hence the name.
