There is no animal that is a cross between the kangaroo and the wallaby. Although both members of the kangaroo family, each is an entirely separate species, and they cannot interbreed. The wallaroo, another member of the kangaroo family, is a separate species again, even though its name seems to be a cross between 'wallaby' and 'kangaroo'. In size, it is smaller and much stockier than a kangaroo, but considerably larger and heavier than any species of wallaby.
