The Toro Toro no Mi allows its user to transform into a jelly-like substance, enabling its user to flow through small spaces and attack with liquid blasts, as well as let physical attacks bypass the liquid body.
However, the user has no effective physical strength when in liquid form, and cannot transform back into their normal form if they are in a space that their normal body cannot fit in. Because of these flaws, Nami easily captured and sealed Honey Queen in a jar while she was in her liquid form, and thus was unable to escape.
Also, even though most Devil Fruit powers transform the user's clothes along with their body, she always leaves her clothes behind while transforming into liquid, requiring Boo Jack to bring her clothes back to her. Other than that, the user is also affected by the standard Devil Fruit weaknesses.
Honey Queen uses her ability for quick and surprise attacks, as seen when she kidnapped Sanji. She launched a large wave of her liquid against the Straw Hat Pirates, with enough force to cause Sanji to fall off the air balloon. She also transforms into the liquid for quick movements and evasive maneuvers, and to move through a pipeline for long distance transportation in a short time.
