As for the group, well, they look like they were designed by someone over at the CBC Kids promo desk who needed a multicultural group to appeal to the under-three set. After spending the night sleeping in a Sanrio store.
Apparently, the group also includes a Vancouver Island Marmot named MukMuk who is an "honorary mascot." Read more about it at CTV, if you really want to.
Call me cynical, but I think they just designed these to sell souvenirs.
