Summary
Jolyne, Anasui and Yo-Yo Ma are in the middle of the swamps. While Yo-Yo Ma spends his time gulping on mosquitos that still manage to fly away, Anasui stops the boat near a patch of grass as he's heard other airboats incoming. Soon enough, two boats with guards of Green Dolphin appear. Armed with heavy weapons, the guards have learned about the disturbance and are now sweeping the swamps. Yo-Yo Ma has impaled himself on the throttle lever and his moving makes ripples in the water so Anasui rips it out of the lever. Jolyne and Anasui worry about the machine guns on the guard boats since it can destroy their own vessel.

The guards do notice the ripples and head towards the boat, but the group cover their boat and themselves in leaves to camouflage. The guards are fooled, but Jolyne then notices their loose anchoring rope. One of the guards sees the rope in the water as well, but Stone Free has unravelled and tossed the rope into the guards' boat, fooling them again. However, one of the airboat fans blows the camouflage away. Just as the guards prepare to fire on the heroes, Yo-Yo Ma releases a swarm of mosquitos from his mouth, which then sting Jolyne in the face.

The narration begins by presenting the mosquito and notably how they secrete saliva when sucking blood to prevent blood from clotting when they suck it. In the present, the guards start opening fire on Jolyne and Anasui, wrecking their boat and their engine. However, Anasui remains calm. He pushes Yo-Yo Ma into his boat's spinning fan, sending him flying into the guards of one boat and destroying it. Anasui then advances toward the second boat and punches the guards with Diver Down. Thus, the heroes are able to hijack that boat and escape.

The group continues further into the swamps, with Yo-Yo Ma piloting the boat. Jolyne complains about his constant whistling but Anasui asks Jolyne to stop whistling too, confusing her. Jolyne tries to speak but it turns out that Jolyne's tongue is full of holes, which caused the whistling and now makes her unable to speak. She tries to tell Anasui that she's under attack from Yo-Yo Ma but Anasui cannot hear her. Humorously, Anasui begins to mistake Jolyne's strange behavior with an attempt at flirting, leading to her uppercutting him in frustration. Still unsure about Yo-Yo Ma's method of attack, she tries to make Anasui realize that the Stand is attacking them, to no avail. Nonetheless, Jolyne is determined to go through this battle.

Yo-Yo Ma keeps acting servile towards Jolyne, suggesting to make her a short out of frog skin. Meanwhile, Anasui finally notices that something is wrong with Jolyne. For her part, Jolyne tries to figure out Yo-Yo Ma's method. She unravels her skin into strings, catching several mosquitos. She thinks she's figured out the attack but the other side of her face also begins to melt, meaning the attack is different. Jolyne collapses on the floor and tries to warn Anasui by writing "Be All Eyes" but that obscure message doesn't help. Yo-Yo Ma is winning and ominously proposes Anasui fights him.

Meanwhile, F.F. has crawled back into the Ultra Security House Unit whose main hall has been invaded by a giant dead tree. The guards have retrieved D an G and she sneakily approaches D an G from above, perched on the arches. Aiming at D an G, F.F. suddenly spots the priest Enrico Pucci observing the scene from afar.

In the swamps, Anasui has Diver Down punch Yo-Yo Ma releasing another swarm of mosquitos which Anasui kills. However, Jolyne knows that there is another method of attack. Holes begin to form on Anasui's face but he persists. He orders Yo-Yo Ma to move as far on the back of the boat as possible as other holes appear on his arm and neck. Although Jolyne silently warns Anasui about not coming too close to him, he still stomps on Yo-Yo Ma's head and orders him to empty his pocket. Yo-Yo Ma obeys, showing a whole range of items and other critters. All the while, more and more holes appear on Anasui's body. Anasui then asks if Yo-Yo Ma is here to kill Jolyne, which he confirms; Yo-Yo Ma adds that he will kill him as well if he stays, causing Anasui to violently chop into Yo-Yo Ma's head with Diver Down, which seems futile at first. Jolyne finally realizes that Yo-Yo Ma has poured his acid saliva into the water and thus when the boat moves, the waves spray the heroes with acidic water.

Anasui then orders Yo-Yo Ma to speed up the boat, which Jolyne deems dangerous. Strangely, Yo-Yo Ma feels unwell. He begins to croak and lay on his back before crawling on all fours. Even more strangely, Yo-Yo Ma instinctively tries to eat insects and fears the birds above. It turns out Anasui sabotaged Yo-Yo Ma by wiring his sensor to a frog's brain, overwhelming it with the frog's instinct. Yo-Yo Ma begins to lose its focus and is effectively neutralized.

In the prison, F.F. faces a conundrum. She hesitates to kill D an G right now although his death is a priority, but is also very intrigued at Enrico Pucci's presence. Hidden in a corner, Pucci counts primary numbers and tries to analyze the situation. Since D an G is severely wounded, he supposes that Jolyne Cujoh is still alive and that the plant debris is the sign of something incredible in the next step of his plan. Pucci gets ecstatic and plans on interrogating D an G, but for the moment, he slots a music disc into Guccio's corpse, which sings Handel's Messiah.

Meanwhile, the guards begin evacuating D an G into an ambulance while they go search the building. Pucci goes to the ambulance but then recognizes one of the medical staffers as F.F., who's put on a disguise and is going to kill D an G. F.F. holds him at gunpoint and shoots, but suddenly a guard rushes in and holds F.F.'s arm, making her miss. The guard has been brainwashed and controlled via a DISC created by Whitesnake. F.F. realizes that the Stand is here and then Pucci ominously reveals himself, walking towards the ambulance although a fence separates him from F.F. Pucci forces F.F. into a dilemma: either F.F. kills D an G first or him.
