The Dalaran Sewer Turtles, a nod to the Teenage Mutant Ninja Turtles, are one of the more iconic easter eggs found in Dalaran. With the destruction of Dalaran at the beginning of the War Within, the fate of the turtles is unknown… until now! Learn how to find them and even get one of them as a Battle Pet — the Dalaran Sewer Turtle!
You must go through a very quick side quest to obtain the Dalaran Sewer Turtle Battle Pet. In Isle of Dorn, just west of Freywold Village, you will find a Dalaran Sewer Turtle accompanying the Dalaran Sewer Rat, who happens to be injured.
By talking to the Sea Turtle, it will ask you for a few fish to help heal the Sewer Rat. First, it will ask for 5 Dornish Pike (fished from Calm Surfacing Ripple schools in Khaz Algar), and after a bit, it will ask for 1 Goldengill Trout (fished from Glimmerpool schools in Khaz Algar). Once you bring both fish to the Sewer Turtle, the Sewer Rat will be all better, and they will move on to locate the rest of the Sewer Turtle family.
Later on, you will find the Sewer Turtles in Dornogal, by the Stoneshaper's Atrium area — All four of them reunited, together with the Sewer Rat! Talking to «Leonardo» (the blue bandana turtle) will give you an option for the turtles saying thanks, dropping a bag containing the Sewer Turtle Whistle!
The Dalaran Sewer Turtle pet isn't much different from other turtle battle pets, but it is a 1-in-4 battle pet — With the turtle containing a different scarf every time its summoned!
