Hello Greg, I'd like to ask you a question on the Shallows Cat's visual depiction/appearance.
So according to the BIONICLE: Encyclopedia Updated and the BIONICLE: World, the Shallows cats are panther-like Rahi, and a smaller & sleeker cousins of the Muaka cats.
In the unreleased BIONICLE: The Legend of Mata Nui game, there's a non-canon Rahi, resembling a smaller version of the Muaka, called Wolfrat, found in Ko-Wahi.
Here's our little Rahi:
So could this "Wolfrat" be the official model/representation/visual depiction of the Shallows Cat?
For the LOMN was never released and its content is non-canon, it wouldn't mean that any of the Shallows cats were ever on the island of Mata Nui, But we would have an official model for a canon Rahi.
Thanks for your time!
