Fun Fun Fun

Ojiro Sasame commands Fun Fun Fun, a Stand with a bell-shaped, vertically ribbed head, based by Araki on a lemon juicer, and a gaunt humanoid torso cut off around the hips. Dangling tendril-like legs end in disc-shaped feet, thin sharp shoulder pads sit above, and assorted studded and Q-shaped pieces decorate its head, collar, chest, and loose belt. The overall motif is that of a stethoscope, reflecting how it eavesdrops to sense what is happening on the floor below. Colored art shows it in white and purple.

Fun Fun Fun controls its targets by exploiting their injuries. If a person suffers even a minor cut while standing physically underneath the Stand, especially on a hand or foot, the blood congeals into a symbol shaped like a broken circle enclosing an inward-pointing triangle. The marked limb then answers to Ojiro, who can move it however he likes. Should a mark land on every hand and foot, he effectively owns the victim's movement, though they keep the freedom to speak and to shift unmarked parts such as the shoulders. Once fully seized, a victim is pinned below him and trails after him if he walks off, and the marks bulge with volume whenever he actively works them.

The power carries strict conditions. Ojiro has to remain above his target and stay conscious of where they are, so a person can carry all four marks and still move freely if he loses their location, which is how Josuke escaped by soundproofing the room he was trapped in. A wound will not even convert into a symbol unless Ojiro is positioned over the victim at the time. Later on, the Stand is shown able to place its mark on a limb without any injury at all.

Ojiro Sasame is the lone user of Fun Fun Fun. Since the Stand has no fighting strength of its own and its setup is fiddly, he tends to use it to torment everyday people and to rig traps that let him take an enemy under his control.
