The term "Oz" is a common nickname for Australia (as it can be pronounced "Auu-zee"). This card is thus aptly named, being a fusion of two of the most recognizable animals from Australia - the kangaroo ("Des Kangaroo") and the koala ("Big Koala").
This monster wears the same vest and sneakers that "Des Kangaroo" does.
