Elvis is the true king of rock and roll! This will show you how to dress up like Elvis on Club Penguin.
Steps
Buy the "rocker" wig which is a hairstyle very similar to the one Elvis had.
Hold an acoustic guitar. He usually used acoustic.
Buy the supernova suit in the clothing catalog.
Buy yourself black sunglasses.
Go to areas on Club Penguin and say, "I'M ELVIS".
Some penguins might pretend to think you are real, other will say "no".
Give performances at the lighthouse stage and the pizza parlor, and any other area.
That's it!
Tips
If you make preferences on CP, try singing (actually typing and sending lyrics of) songs Elvis did (Heartbreak Hotel, Jailhouse Rock, Are You Lonesome Tonight, etc.).
