1: [Young]
The Ziggurab's stone shell evolved to protect its sweet, squashy insides. Telescoping shut when startled or sleeping; this creature is as tough as a fortress.
2: [Adult]
Despite its solidity, the Ziggurab is agile and energetic. Using the resonance of air pockets and specially evolved appendages, it produces a huge array of rhythmic sounds and effects.
3: [Prismatic]
This Ziggurab returned from the Prism Gate forever changed! While its overall crustacean appearance has been preserved, it has been separated at the molecular level into two-louse like beings trying to pulverize a rock - extraordinary!
