Goo Goo Dolls

Goo Goo Dolls (グー・グー・ドールズ) is the Stand of Gwess featured in Stone Ocean.

Appearance
Goo Goo Dolls is a tiny humanoid Stand no more taller than a mouse with a cylindrical head and robotic arms. It has thorn-like structures on its head and upper torso with a set of sharp teeth from its always open mouth. Goo Goo Dolls possesses mechanical joints.

Its design is based on a mummified monkey.

Personality
Goo Goo Dolls displays a feral personality, being able to mutter the sound "Goo" but otherwise attacking its enemies with reckless abandon. It may have some cunning as it is stated to take advantage of its power in a fight.

Ability
Goo Goo Dolls is very weak due to its reduced size and isn't suited to fight other Stand Users, but its power to shrink people is perfectly suited to Gwess' habit of bullying those weaker than her and its sharp claws are enough to tear shrunken people apart.

Goo Goo Dolls typically hides near a shrunken victim, somehow being able to even hide in the same animal skins Gwess gives to her "pets" and will automatically attack them if they disobey Gwess' orders.

Size Reduction
Goo Goo Dolls has the ability to reduce the size of anyone within its range. It is hinted that it will work only on those Gwess focuses her desire for friendship but also control.

When in range, Goo Goo Dolls can instantly shrink its victim to the size of a mouse, the size reduction is instantaneous and unnoticeable at first by the victim. On the other side, once a shrunken victim goes far enough from Gwess, they will grow back continuously.

Gwess typically uses that power to get herself makeshift pets she hides inside animal skins and play with.
