Pavlov is a penguin from Final Fantasy Crystal Chronicles: My Life as a King. He follows King Leo around and offers him advice.

Story

Pavlov first appears in Padarak one night knocking over King Leo as he bursts out of the Castle. He begins to claim the land belongs to him and demands King Leo leave. King Leo then chases Pavlov through the Kingdom until he is eventually caught. When Chime and Hugh Yurg try to introduce themselves to Pavlov he reveals that he already knows their names and denies to answer any of their questions. The next morning, he decides to help King Leo but will not reveal his reasons, other then he is keeping a promise he made. He will follow King Leo around and sometimes offer him advice while keeping records about the kingdom and adventurers.

According to the townspeople of Padarak, Pavlov was rescued from drowning in a lake by King Epitav, Leo's father. It was Epitav who taught Pavlov how to speak, and that is why he shares many of Epitav's personality traits.
