Corn Sky mostly visits the server Abominable and Blizzard.
Corn Sky logs in every day. If you are on those servers then you might get lucky to meet him. Sometimes he goes on a different server so he can meet a Club Penguin mascot. Sometimes if you are lucky he will visit your igloo and like it. You could also get a chance to meet Corn Sky on the Club Penguin app. However, since Club Penguin closed in March 2017, this is no longer available.
