Captain Toad: Treasure Tracker is steadily getting closer and closer to release on Switch and 3DS, but there appears to be one very strange omission from the original Wii U release.

In a hands-on preview of the game, the folks over at NintendoWorldReport have mentioned that the four Super Mario 3D World-inspired levels present in the original game have been replaced with four levels featuring different Super Mario Odyssey Kingdoms. We've known about the new Super Mario Odyssey-inspired content for a while now, but it was assumed that this would be an addition to the main game - not something to replace already existing levels.

Of course, it would make sense for Nintendo to put any nods to Super Mario Odyssey front and centre in the new release, hoping to generate more sales across the two games thanks to the crossover, but getting rid of content referencing another game seems like a very odd decision. Hopefully the levels are still present in some way later in the game - perhaps as unlockable content. We'll have to wait and see when the final game arrives next month.

If you want to get a taste of Captain Toad before it releases on 13th July, make sure to download the free demo that has become available on the eShop today.
