Amarus are the second enemies encountered in the game. Found after Dakus in the same locations.

Amaru is a tall, lizard-like alien with smoke green scales, vis vis countershading, and orange mane running along the back of his head, down his spine to the base of his tail. They are the second enemy type you will encounter. They only wear a brown loincloth, with only their nuts being visible, and hold a large sex toy weapon, which they swing like a sword. It appears to be made out of the same material as the Daku's dildo knife, implying that they are working together in the Gerrabacco.

Amarus can be encountered in the Sheo Islands Beach and the Southeast Beach. They share these locations with the Dakus and appear in the Game Over scenes for Southeast Beach

They have a swing attack that is slower but tougher than that of the Dakus and a grapple that comes out very quickly in front of him.

For their seductive taunt, Amaru will seductively lick the side of their dildo sword which will cause a small heart to appear on the tip of the weapon. The heart will fall on to the ground and begin rolling across the floor at high speeds dealing minor damage to Joe and raising his Lust meter. The hearts will stop if it collides with Joe or any walls, meaning that they can potentially be used from elevated platforms.

With version 17.000, Amaru gained their seductive taunt.

With version 18.200, Amaru has one multigrab with Daku.

With version 18.400, Amaru gained a second multigrab with another Amaru.

With version 1.06.001, the Amarus had their animations updated with new versions that include additional segments and improved detail. These replaced their animations during gameplay. If the player had already seen the old animations on their save file, they could still see the old ones in the gallery.

• Amaru is the first enemy with a “hyper”-sized penis (though it leans towards the lighter side). It is ambiguous whether these are external or internal since they're humanoid in shape yet do not form any obvious bulges as their sizes might suggest.
• Amaru is the only enemy that Joe himself never actually penetrates using his penis.
• In older builds, Amaru used to appear in Treewish Forest and Brask's Jungle.
• A number of Amaru, alongside a single Daku, appear in the Game Over screen for Southeast Beach.
• Amaru was one of the first enemies to have a grapple with a character different from itself.
• Daku was one of the first enemies to have their animations redone after their release, an update after the Dakus did first, these were updated to appear during gameplay but the old ones may be seen in today's builds if players had unlocked them in the gallery before.
