Nintendo has announced a new online challenge will be coming to Super Mario Odyssey.

Dubbed Luigi’s Balloon World, this new challenge has two distinct modes. Hide It Mode sees players be given 30 seconds to hide a balloon for other players to find in the levels of Super Mario Odyssey. Find It Mode turns the table around, challenging you to find balloons hidden by other players. To activate the challenge, you simply have to speak to the green mustache himself, Luigi.

Luigi’s Balloon World will be coming to Super Mario Odyssey in February this year as a free update.
