Deep Beetle - A cave mobility companion

The Deep Beetle is a passive cave mob that adds a new way to explore underground areas. While the surface and Nether have unique travel options, caves currently lack their own mobility system. This creature would allow players to move along walls and ceilings, making it easier to navigate vertical and tight cave spaces. It would be slow and fragile, focusing on careful exploration rather than speed or combat. The Deep Beetle would add more life to caves and create a unique exploration experience without replacing existing mechanics.
