Pearl Jam

Pearl Jam (パール・ジャム) is the stand of Tonio Trussardi featured in Part IV: Diamond is Unbreakable.

Appearance
Pearl Jam is a stand possessing multiple (at least six; almost certainly far more) bodies, each body appearing as a cross between a head of garlic and a pearl onion with arms and a face. The bodies are extremely small, as they need to be ingested to do anything.

Ability
Repair via Ingestion: First, Tonio examines his customer's hands to see what ailments he/she suffers (apparently a granted power of Pearl Jam, though similar practices exist in Chinese traditional medicine, and Tonio had previously been to China). From this, he knows what foods to prepare. The meal is served one course at a time, with Pearl Jam's bodies inside. Once inside the "patient"'s body, Pearl Jam invokes a sense that whatever is being eaten is extremely delicious (even if the consumer dislikes the general taste, such as Okuyasu's aversion to spicy foods) to make sure that the food is continuously eaten. It then uses the incoming raw material to repair and replace damaged and diseased tissue, forcibly ejecting the damaged tissue at one point, such as opening up one's belly for a short while to eject replaced intestines.

Trivia

 * Unlike most stands that Josuke meets, Pearl Jam was not awakened by an Arrow, but by Tonio's zeal to perfect his culinary arts.
