The Great Hunger: The Builder’s Heavy Mount

If they were to consider adding the Great Hungry One, they could make it a large mount that, when mounted, would eat everything in front of it. Afterward, you could access its inventory and take whatever you needed; anything left over would disappear from its inventory after five minutes (because it ate everything). It would be the ideal mob for builders when flattening. Its acquisition method could even be similar to the Sniffer's, only this one would be found in suspicious gravel in the Lush Caves, obviously. It would be five blocks wide and three blocks tall. The "digestion" would only begin when its 18-slot inventory is full, and it could only eat blocks when the player is mounted.
