SO TO CELEBRATE THE RETURN OF THE OG LEVIATHAN, I BOUGHT THIS COOL LAGIACRUS FROM THIS AWESOME ARTIST: https://bsky.app/profile/karvivore.bsky.social (18+ content warning)

They are a species of Lagiacrus that have gained the ability to inflate itself to float and use air based attacks via a gas sack that developed instead of the usual thunder sack. It also has the ability to produce a sleeping gas as long as it has a decent diet of monsters that can produce a good amount of the gas and their preferred prey for this are Nightshade Paloumu. They call also eat Sleep Herbs to achieve a similar effect but would need a large amount to do so and some for meat to go with it.

This one particular individual is a monstie named Skye.
