As of my last update in October 2023, there haven't been any official updates or features in Minecraft that specifically relate to getting a character like Marshall from Paw Patrol. Minecraft updates primarily focus on gameplay mechanics, blocks, mobs, and various gameplay elements rather than integrating specific characters from media franchises like Paw Patrol.
If you're looking to create custom content or mods that incorporate characters from Paw Patrol, you might want to explore community-created mods or resource packs. However, for official Minecraft gameplay, there isn't a method to obtain Marshall using items such as A Pale Wolf, bones, Yellow Dye, or Red Wolf Armor.
To get the latest features or updates directly from Minecraft, consider checking their official website or update notes.
