Obsessive about cleanliness: He is extremely tidy. He spends most of his time cleaning everything (his nest, his friends, objects, etc.) using his tail like a feather duster. He cannot stand dirt.
Sweet and affectionate: It is friendly, sociable, and likes to be near humans and other Pokémon.
A little nervous/perfectionist: Sometimes appears anxious or stressed if something is not perfectly clean or tidy.
Curious: He loves to investigate new objects, as seen in the picture with the book.
Occasional shyness: Although sociable, he can also be somewhat shy or easily embarrassed.
