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 bodies; each appearing as a cross between a tomato and a pearl onion, with arms and a face. The bodies are extremely small (as they need to be ingested to do anything); as well as seemingly invisible whilst bound to Tonio's dishes.

Personality
When uncovered by Josuke and Crazy Diamond, they appear to express surprise, along with vocalizations like "meshaa!"/"meshii!" and "gii!".

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 may or may not help invoke the sense that whatever is being eaten is extremely delicious (even if the consumer dislikes the general taste, as with Okuyasu's aversion to spicy foods) to make sure that the food is continuously eaten (though it is possible that Tonio's inherent skill as a cook facilitates this part of the process).

The Stand then uses the incoming raw material to repair and replace damaged and diseased tissue, forcibly ejecting the damaged tissue at some point, such as opening up one's belly for a short while to eject replaced intestines. Once the tissue is expelled and repaired, the customer's body comes back to normal as if nothing had happened, but with the problem now completely solved.

Trivia

 * Its design is based on a tomato and an unspecified Italian vegetable.
 * Unlike most Stands that Josuke meets, Pearl Jam was not awakened by an Arrow, but by Tonio's zeal to perfect his culinary arts.
