In Super Paper Mario, Mario and Tippi have to see Red in order to get past the bridge that leads into Yold Town. However when they arrive in his house he appears to not be there, but if Mario flips into 3D he will find Red crying because he has gotten stuck in the 3D dimension. Mario can then pull him back into 2D, then Red asks what Mario's favourite color is. If Mario answers Red he will be let into Yold Town.
