Wendigo are giant, beige, dog-like creature who's mission is to attack Iota/Atoi. They are often tricked into dashing into a pop-up present, which serves as a prison for them. They are found in Sogport. Not all of them want to attack Iota/Atoi. There is one, a Baby Wendigo that helps Atoi and follows her around.
Wendigo are able to run very quickly, as well as thrown balls to great distances. They are not able to escape pop-up presents.
