Club Penguin Loreさんのイラストまとめ

On March 7, 2005, he completed his ship, dubbing it the Migrator. He planned to leave in the morning, and return the next month.

On March 8, Rockhopper was touched to see a crowd had gathered at the Dock to say their goodbyes. Even the Penguin Band was there performing for him.

Intrigued by his new look, a creative penguin approached him. They asked to create a commemorative painting before his departure. Rockhopper was happy to oblige, striking a pose atop the ship's deck.

Rockhopper built for many long months, growing a long black bushy beard in the process. As his ship neared completion, he decided to sport a fresh new look.

He donned the bold new red body paint and a captain’s hat, officially adopting the title “Captain Rockhopper.”

Around 2003 the penguins were introduced to igloos, popularized by the Penguin Band's debut. Many began building igloos of their own. Rockhopper took part in this craze, constructing an igloo he could call home.

It's been right in front of us all along.

Honorable mentions.

Interesting catch by @MetaVaria - the fireplace furniture item does feature a family portrait.

@patoscript2 I’ve actually speculated that the Welcome Room may be near where the original EP took place, being flat, empty, and located near water. I left it out as it's more of a headcanon rn. If it were true though, it could serve as a sort of “birthing/spawning grounds” for the penguins.

We can deduce from all this that the penguins' natural-born color is blue.

Of course, CP's early art was pretty inconsistent, so the exact hue is up for debate. However, it's safe to assume that the shade is "Old Blue", given the color's in-game unavailability & testing usage.
