The Egg Nautilus is a mech-like device created by Dr. Eggman that resembles a nautilus.
The Egg Nautilus' tentacles are capable of uploading viruses into computers and are equipped with metallic claws at the ends that can be used to crush objects. It can also fly by sitting upright and using its tentacles like helicopter blades to soar into the air. (StH: #180)
- A similar mech (resembling a squid more than a nautilus), appeared in issue #38 of the Sonic X comic.
