The Sniffer as your new Archeologist buddy

I'm pretty happy with Sniffers as they are now, but I do wonder what else they could bring to the game, so I've thought of a couple fun ideas that could be implemented. For starters, when a Sniffer egg is hatched, there would be a chance for 1-2 egg shells to drop along with the Snifflet. These items could be placed down in groups of four quarter pieces to create an intact sniffer egg for decoration. I also thought of the idea of riding a sniffer, maybe having to craft a special harness for them similar to the happy Ghast. Riding a Sniffer would be very slow, but could allow the player to utilize a new ability. I have two example of what each said ability could do if both couldn't be added. 1.) Digging The Sniffer is all about digging, by charging the jump button like with regular mounts, the Sniffer is able to plow through dirt and possibly stone in a short area in front of them. 2.) Sniffing The Sniffer believe it or not, sniffs. I think it could be fitting to find more ruins to explore using the Sniffers strong sense of smell. By charging the jump button while mounted, the Sniffer is able to locate nearby structures such as ocean ruins, trail ruins, desert wells and possibly temples. If a valid ruin is detected, a question mark could be displayed within the new locator bar in the direction of the ruin for a short period of time. These ideas would be added on top of the ancient seed findings abilities, and would not override anything already implemented.
