Unfortunately, this is false. The X user who published the claim, @RizzyDuck, can confidently be assumed to be a parody account (their bio says "[m]y pronouns are Quack/Attack"). Many of their posts are satirical in nature, and feature use of edited images (like the one used in the original post showing the Fortnite skin of the Duck). Further, a quick Google search will show zero mention of a collaboration effort between the University of Oregon and Fortnite--lack of a source here is almost as good as having one. Should anything like this every come to fruition, there would be plenty of media surrounding it.
