Emperor Sandworm

Overview
The Emperor Sandworm is a new mission boss added in the 2.9 Patch. It is the biggest, meanest, toothiest, and also apparently smartest sandworm ever encountered. Floyd calls it the Emperor Sandworm because of its ability to control other sandworms and coordinate them intelligently against the Outpost's infrastructure, while a local Big Game Hunter named Bogan Hunter dubs it the "Ridgy-Didge."

The "Ridgy-Didge" lives up to Bogan's hype. It has 1800 total hp and armor and 4 separate attacks, plus it has a large group of Groundshakers and Elder Sandworms backing it up. The attacks include powerful versions of the Groundshaker's spit and bite attacks, the Elder Sandworm's spit attack, and a checkerboard strike.
