Nintendo’s Super Mario characters will soon be invading the blocky world of Minecraft… if you play on the Wii U, that is.

The update, dubbed Super Mario Mash Up Pack, will feature 40 new character skins, allowing gamers to replace standard Minecraft characters with those from Nintendo’s popular franchise. Expect to see favorites like Mario, Luigi, Toad, Diddy Kong, Yoshi and Princess Peach as well as familiar villains such as Wario, Bowser and Waluigi, among others.

The free update also includes new world textures that replicate many of the classic settings from select Mario games, various item skins and 16 pieces of theme music from Super Mario 64.

The collaboration marks the first time Nintendo has licensed its IP for use in Minecraft and further serves as a testament to Minecraft’s mainstream appeal.

When Microsoft announced its acquisition of Minecraft in September 2014 for a whopping $2.5 billion, many felt the company overpaid for the property. Microsoft has since proven us wrong, however, as it has positioned the game for success in the education sector, converted it to the virtual world and proved that it will make a killer HoloLens app.

The Super Mario Mash Up Pack will be available to download beginning May 17. Nintendo is also working on a retail version of Minecraft for the Wii U that’s scheduled to hit stores on June 17 (the Mario DLC will be included on the retail game disc). If you’ve yet to grab Minecraft on the Wii U, expect to pay $29.99 for the opportunity.
