Sand worm

This colossal worm dwells in the Sandcaves. Only one can spawn per run. It can burrow through the background and come back to the front. It has unique advanced worm parallaxing technology which makes it look like it is moving on the z axis. This mini boss is mostly weak to poison but can be killed by other means. It also drops a health up and a decent mini boss wand.

The worm itself deals damage by collapsing terrain dealing collapse damage and can bite, based on its biting animation.
