Hayden Panettiere's New Pet Dolphin

Heroes star Hayden Panettiere meets and greets fans, including a svelte Darth Vader and an Imperial storm trooper, at the Big Apple Comic, Toy, Art and Sci-Fi Expo at the Penn Plaza Pavilion in Manhattan on Saturday.

While signing for her fans, Hayden received a cute dolphin plushie – a reference to the news she recently shared with E! on Wednesday: “I learned that they have an arrest warrant out for me in Japan… We just found out.”

Hayden, with several other activists, had attempted to block a dolphin pod from being hunted by fishermen in southern Japan in October 30.
