Here is some information about Rookie from Club Penguin:
Rookie
A proud and loyal member of the Elite Penguin Force. Rookie has been involved in countless missions, including the top secret Operation: Herbert's Revenge.
He's always eager to protect the island, even if he sometimes makes mistakes.
- Can I meet Rookie? Although he rarely appears on the island, Rookie often sends classified messages to Elite Agents on the Spy Phone. He first appeared in person at the 2011 April Fool's Party – when he accidentally unlocked new rooms in the Box Dimension.
