Turtle graffiti art
Tortoises or turtles were shell-covered reptiles able to retract their heads inside. Graffiti was sometimes drawn by clone troopers on their All Terrain Tactical Enforcers, illustrating the vehicle as a turtle.
The special features of The Clone Wars's season four revealed that the Nautolans located on Glee Anselm would have been shown living atop enormous turtles during the season two's "Children of the Force" episode.
