A pigtopus is Ixia 's favourite animal; though it is actually a nonexistent, tiny pink octopus with the nose of a pig.
As a child, Ixia loved taking care of the animals that people in her village kept. One day, she just happened to notice a little piglet running around with a little girl's pink dress. Due to her bad eyesight, she mistook it as an octopus with a pig's nose, which she described as "the cutest little thing I've ever seen" and self-proclaimed it as a real animal, then making it her favourite.
The pigtopus appears randomly throughout the story in the form of hats, dolls and such.
