Boxmas, the blend of Christmas and Boxing Day, a holiday that transcends timezones.
There is no better emblem than a kangaroo for Boxmas, they are already stereotyped by some as a boxing type, so why not make a boxing roo of a different type.
Boxmas Roo's head is a gift box wrapped with a bow and top with a santa hat. Meanwhile in the pouch is an infinite amount of gifts. Rather or not they are empty or not is yet to be confirmed :p
