He says "bard".
No. You have to beat all the planets, and get all three knights with you, before going to the lair of the Binary Bard (X-11 Y-82). (see related question)
You can't costumize him in Astro Knights Island or Super Villain Island but you might search the common rooms for someone with his face.
The Princess has been captured before the start of the quest on Astro Knights island, and is not seen until the final battle in the lair of the Binary Bard.
The Binary Bard is on the Giant Asteroid near coordinates X-8 Y-82. But you cannot reach him until all three planets have been defeated and you have all three space knights with you.
You still have to go to the other two planets (jungle and fire) and defeat their robots. When you have all three knights, go to the asteroid at X-11 Y-82 to face the Binary Bard.
The "Binary Bard" half-robot face is not currently in the Poptropica Store, but some users copied it when the "real" Binary Bard frequented the multiplayer rooms prior to the release of Astro Knights Island.
