Found in the files of Super Mario 3D World are two icons depicting an orange-colored Mario that are similar to the character icons. It is unknown what these would have been used for, but it is possible that they would have served a similar purpose to the Super Guide in New Super Mario Bros. Wii and Donkey Kong Country Returns. In addition to this, there is a hand icon, most likely planned for a fifth player to control an invisible hand, similar to the Boost Mode of New Super Mario Bros. U. The final version has a similar feature, but it is used while controlling a character, making the icon useless.
