Sara Sara no Mi, Model: Axolotl

The Sara Sara no Mi, Model: Axolotl (サラサラの実 モデル:アホロートル) is a Zoan-type Devil Fruit that allows its user to turn into an axolotl hybrid and a full axolotl at will. "Sara" is short for "saramandā" (サラマンダー), which means "salamander". It was "eaten" by Smiley.

Strengths and Weaknesses
Due to it being a Zoan type fruit, the Sara Sara no Mi allows the once-inanimate user sentience and movement, actions that would normally be impossible for Smiley, who is little more than condensed gas.

Being a Devil Fruit power, it grants the user it created the standard weaknesses that of a Devil Fruit; this also creates an instinctive fear of water for Smiley.

Usage
Smiley is seen using its powers for movement and transforming into an alternate form that suits the situation, such as after Kinemon slashed off globs of Smiley. Its sentience is also preserved within pieces the main body may separate from itself, as seen when Smiley launched over many smaller pieces of itself across the lake of Punk Hazard, all of which displayed the same degree of independent thought and reacting to their surroundings as the main body would have.

Trivia

 * This is the first Zoan type fruit based on an amphibious species, which is an oddity given that Devil Fruits have a weakness towards water. This model is particularly odd since, unless they are artificially induced to undergo metamorphosis, axolotls remain aquatic their whole lives. Also, the name means "water monster".
