It seems there might be some confusion surrounding the character Moby in the Paw Patrol series. Let me clarify!
Moby is introduced as a character in the "Pirate Rescue Pups" special of Paw Patrol, and he starts off as a devious pup. However, as the storyline develops, Moby redeems himself and becomes an ally to the Paw Patrol team. After the events of "Sea Patrol," Moby indeed joins the Paw Patrol in the "Pirate Rescue Pups" missions.
In the series, he wears a distinct uniform that includes white, gray, black, and red colors, along with his unique pup tag. He also has his own specialized vehicle that is slightly different from the others to suit his character and missions.
Overall, Moby's journey is one of redemption, illustrating themes of forgiveness and teamwork, as he helps the Paw Patrol with their adventures. If you have any specific scenes or aspects of Moby you'd like more details on, feel free to ask!
