Fun Fun Fun
Fun Fun Fun (ファン・ファン・ファン Fan Fan Fan) is the Stand of Ojiro Sasame, featured in JoJolion. When Ojiro stands above someone and their limbs are injured, Fun Fun Fun marks the wounded limb and can control it.
Fun Fun Fun possesses a bell-like head, lined vertically, and a humanoid torso; its waist utterly emaciated, truncated mid-hip. From its hips hang four small leg-like vestiges, while it stands on four disc-like feet from four long, bending legs or tendrils hanging from its shoulders; capped by four thin, sharp shoulder pads. Two roughly Q-shaped pieces rest atop its head, facing its sides, with two smaller shapes on its collar, one large in the center of its chest, and one small on the buckle of a thick, studded belt that sits loosely on its hips.
It has the image of a stethoscope, since it listens in to figure out what's happening on the floor below it. Its head is based on a lemon juicer.
Fun Fun Fun is white and purple in the colored manga.
Because Fun Fun Fun's ability is difficult to set up, and it has no physical ability whatsoever, it is unsuitable for direct combat. Ojiro typically uses his Stand to torment ordinary people, and prefers to set up traps to take control of an enemy.
From above, Fun Fun Fun can control a target's movements through their wounds, similar to a marionette.
If a target incurs the slightest injury on their body while being physically under Fun Fun Fun, notably the hands or feet, the blood flowing from the injury clots to form a symbol in the shape of a "Q". The corresponding injured limb then falls under Ojiro's control, allowing him to move it as he pleases. If a mark accumulates on all four of the victim's limbs, the victim is essentially under Ojiro's control absolutely. Nonetheless, the victim can still freely talk and move other unmarked parts of the body like the shoulders. Moreover, once Ojiro takes complete control of a victim, they are locked beneath him and will follow him if he moves.
The marks seem to pop out and act as pins whenever Ojiro is pinning them down.
The marks on the injured body part gain volume when Ojiro actively controls a target.
However, Ojiro must be physically above his victims to control them and be conscious about it. One may stand beneath him with all four limbs marked and be free of their movement if Ojiro loses track of their position (for instance, Josuke made the room he was trapped in soundproof in order to throw Ojiro off). An injury doesn't transform into a symbol unless Ojiro stands above the victim.
When Ojiro later returns, Fun Fun Fun is able to place its mark on the victim's limbs by touching them without needing to injure them first.
