Toro Toro no Mi

The Toro Toro no Mi, is an anime only Devil Fruit, that gives its user the ability to turn into a liquid-like substance. Toro means liquid and the substance the user turns into isn't water. It was eaten by Honey Queen.

Strengths and Weaknesses
Interestingly, this Devil Fruit doesn't seem to be very powerful, despite its status as a Logia. Nami easily captured and sealed the user in a bottle, who did not seem to be able to escape. The bottle was however somewhat compact meaning there is no space to move nor transform back, and since she is liquid it means that she cannot increase her mass to get out. Nami also properly sealed the bottle with a bottle cap and taped it after that, meaning she was stuck in it.

Also, even though Devil Fruits transform the user's clothes along with their body, she always leaves her clothes behind while she transforming into liquid. Other than that, the user is also affected by the standard Devil Fruit weaknesses.

Usage
Even though this fruit's power is inferior for a Logia-class, Honey Queen can still use her power as a quick attack, as seen when she kidnapped Sanji.

Trivia

 * This Devil Fruit seems to be inferior and unique for a Logia-class for multpile reasons:
 * It seems to be incapable of high-level destruction.
 * It renders the user to be vulnerable to capture.
 * Unlike a typical Logia Devil Fruit, this one doesn't seem to grant the ability to tap unlimited amounts of its element from its user's body, since after attacking Sanji with a liquid splash from her hands Honey Queen had to re-absorb it.
 * Though Devil Fruits in general usually transform a person's clothes in accordance to its powers, this one seems to differ, as Honey Queen always leaves her clothes behind while transforming.
 * This Devil Fruit, along with its fellow non-canonical Ame Ame no Mi, are the only known Logia-class that controls liquid phase elements.
