It was confirmed a while back that a Wii U version of Octodad Dadliest Catch was in the works, though we barely hear any news about this games progress. Under the cover of darkness Octodad awkwardly slipped its way out of development and to Nintendo ready to be sorted out for release, IGN confirms this news that Octodad is currently with Nintendo for certification.
From what I can tell the game will release on the Wii U eShop for $14.99 though this exact price has yet to be confirmed. As of yet we don’t have an official release date though once Nintendo has finished their process one should be quickly confirmed.
