The Pink dog that happens to be dishing on Wooser himself during the Awakening Arc.
Not much is known about Oshirase Wooser's past, but she happens to be the reporter for anything major that happens with Wooser and his pals and has yet to encounter the other characters of the series.
Oshirase Wooser is based on the avatar of the official Twitter account for the "Wooser's Hand-To-Mouth Life" franchise. She was brought to life as an original character as of Episode 3 of the Awakening Arc.
Oshirase Wooser is a dog-like creature just like Wooser and Darth Wooser and also doesn't appear to have a mouth at all (but she can speak and eat just like most of the animals of the franchise). Her entire body is pink and wears a bow in a darker shade of pink.
