The Guardian Dog is a character involved in the play Secrets of the Bamboo Forest in Club Penguin. He is a dog that guards the castle, and only lets penguins who have the Feather Pin in. He is also Phoenix Queen's guard. When he waves, he becomes a statue.
"A loyal guard to the Phoenix Queen and when he waves, he becomes a statue!"
He appeared in a sketch for the What's New Blog as a sneak peek. When the sketch was shown, some penguins thought he was a lion, as shown in the blog's comments.
