Her name relates to "Waltzing Matilda," a popular song in Australia, where kangaroos come from. Her initial catchphrase, "wee baby," refers to a joey, which is a reference to her joey, which she carries with her.
Her Japanese name, Azaraku, may possibly allude to the Japanese word 痣 aza; bruise (referring to the purple markings on her body). Azaraku can also refer to "Eko Eko Azarak," a Wiccan chant referred to the "Witch's chant" performed on Samhain.
Mathilda is a dark gray kangaroo, with a joey in her pouch that mimics her emotions and appearance (like the other kangaroos). She has a charcoal gray body and the inside of her ears are purple. She has purple paws, white feet, a purple mouth, a gray ringed with white tail, and big yellow eyes with red pupils. She looks angry most of the time, same with her joey. Mathilda initially wears the U R Here shirt. She has a similar look to Grizzly, Hopper and Roscoe, due to her eyes and fur.
Below is a brief description of the snooty personality. For more information, click here.
Mathilda has a snooty personality, which means she loves make-up and gossiping. As a snooty villager, Mathilda will first appear rude and arrogant towards the player, often talking about herself and her own experiences. She also speaks about the style and appearance of other villagers, usually other female villagers such as normal, peppy, and other snooty villagers. She will soon warm up to the player, confiding in them about their own feelings but still keeping subtly rude. Mathilda will not get along with lazy villagers due to them not caring about their appearance or the lazy villagers hating what she eats, and she won't get along with jockvillagers because they will question her on her physical appearance and they won't worry about fashion. However, she will get along with cranky villagers due to their similar rude personalities, and usually normal villagers as well.
