Per the licensing page, anyone can freely reuse Wikia content if they provide attribution to the original source. Your best bet I think would be to politely contact them and ask them to include a link to your wiki e.g. in the video descriptions, which would both satisfy this requirement and also help drive new viewers and editors to your wiki :)
