Blue Rock Burrower

The Blue Rock Burrower is a Hardmode worm enemy found in the Granite Biome, completely replacing Granite Burrowers, similarly to how Giant Worms are replaced with Diggers. The Blue Rock Burrower and the Granite Burrowers also share the same kill count and banner, so banner collectors can obtain the banner if they didn't obtain it yet after switching to Hardmode. The worm is much larger than the worm shown in the preview image, as it has about 15 segments.

Segments
This worm has ~15 segments, which is larger than most worms and far larger than the preview image, which only shows 3 segments.
