|“||It seems we're inside the turtle.||”|
Coco Jumbo is a small land turtle whose main characteristic is a key-shaped hole on top of its shell, in which a special key allowing people into its Stand can be placed.
Despite being an animal Stand user, Coco Jumbo doesn't display any kind of personality or heightened intelligence whatsoever. It seems to prefer, like all turtles, to hide in small, dark places.

When a special key is placed in the hole on its back, people can access a small room within the turtle.
Coco Jumbo is introduced idling in Naples' train station. At first, Bruno doesn't take any interest in it, looking for a keyhole corresponding to the key he retrieved earlier. Soon, he notices the key hole in the turtle's back and realizes what its power is. During their adventure, Coco Jumbo serves as a room for Bucciarati's gang as they travel through Italy, allowing them to sneak aboard various means of transportation and providing a safe room for any injured protagonist.
Coco Jumbo plays a key role in saving the lives of both Bucciarati and Trish Una during his first encounter with Diavolo. Giorno Giovanna turns the turtle into one of his ladybug brooches using his Gold Experience and hands it to Bucciarati as a tracking device. When Giorno begins sensing that something has gone wrong, he turns the brooch back into Coco Jumbo, whom sucks the Boss into itself, stalling him long enough to allow Bucciarati the time to come up with a plan in order to escape with Trish.
After Coco Jumbo's soul is switched into the dying Polnareff, Coco passed away and the spirit of Jean Pierre Polnareff resides within his body from that moment onward.
- According to JOJOVELLER, its concept might be a reminiscence of a spaceship or Gamera and its carapace is similar to a jigsaw puzzle where to put a key of rare shape.
- Coco Jumbo is commonly referred to as a turtle; however, as a land-dwelling creature, it is more properly termed a tortoise.
- Even in the most recent, updated version of the italian edition of Vento Aureo, Coco Jumbo is still referred as "la tartaruga" ("the turtle"), with no trace of his actual name.
