Slurpuff is a white bipedal Pokémon with a red collar with a spot of red below it, and pink fluffy hair. On top of its head is a red sphere. It has two small, pink feet, a pink face, and a really long red tongue that is usually sticking out. When it opens its mouth, a pair of fangs can be seen on its upper jaw. It has an exceptionally keen sense of smell, being 100 million times that of a human, allowing it to distinguish even the faintest of smells.
A Slurpuff appeared in Volcanion and the Mechanical Marvel, under the ownership of Raleigh. It was Raleigh's companion, and eventually proceeded to become his partner when Raleigh decided to set off on a Pokémon journey by the end of the movie.
Slurpuff and Aromatisse can be seen as parallels to each other: both are version-exclusive pure Fairy-type Pokémon, with Slurpuff being exclusive to X, and Aromatisse to Y, both have Abilities exclusive to them that affect themselves as well as their allies, and both are evolved from their previous forms by being traded while holding a certain item.
Slurpuff is based on the meringue, a dessert made from whipped egg whites and sugar. It is often topped with whipped cream and fruits to create a meringue nest. The red sphere on its head resembles a fruit topping such as a strawberry or cherry. Meringue is also used as a sweet base on other various desserts such as cakes, pies and pastries. Slurpuff may also be based on cupcakes or Japanese-style mille-feuille. Cupcakes are sometimes referred to as fairy cakes, which may be an inspiration for its type. Considering its lolling tongue, nose, paws, and ear-like circular extensions on its head, it may also be based on a dog, possibly a Bichon Frise or poodle.
Slurpuff may be a combination of slurp and puff. It may also be a play on the word surplus.
Peroream may be a combination of ペロペロ peropero (onomatopoeic sound for licking) and cream.
Both names may refer to the profiterole (cream puff), a pastry dessert filled with whipped cream and then topped with ganache, and a sauce.
