I had this idea that's been going through my mind since February. what if Splatoon and Changed had a crossover? I mean, the main story of Changed has similar attributes to Octo Expansion (not to mention that they were both released in the same year), The Latex monsters have similar abilities as inklings and octolings, except they can transfurr you and swim and water (unlike inklings and octolings), Plus, I can imagine some interactions with colin and puro with off the hook, the squid sisters, and the new squidbeak splatoon. Dr. K and Tartar could work something out between them, but tartar would betray him sometime soon. and Agent 8 would have an unfortunate run in with the virus or one of the latex beasts.
Those are just my thoughts. What do you think?
