CLEARWATER, Fla. -- He's 42 years old, a little out of shape and clearly no spring chicken. But clearly there's no one more popular on the field for the Philadelphia Phillies than the Phanatic.

Which is why all eyes at the ballpark were on the furry mascot Sunday for the big reveal: He has gotten a makeover this year amid a legal fight between the team and his creators.

The revamp, unveiled before the Phillies played the Pittsburgh Pirates in their spring training home opener, includes flightless feathers rather than fur-colored arms, stars outlining the eyes, a larger posterior and a powder-blue tail, blue socks with red shoes, plus scales under the arms.

Don't look for any change, though, in the Phanatic's prankster approach, a point the team reiterated with a tweet Sunday afternoon.

Tom Burgoyne, the man behind the mascot, told The Philadelphia Inquirer that "he's still the same old Phanatic, just with a little more sashay in him." He noted that the mascot's fur color, jersey, hat and overall look have "changed a little bit over the years."

Early reviews were mixed. Some eagle-eyed fans liked the old version more, others said the changes weren't that big of a deal.

The team and the mascot's creators have been sparring in court ahead of the June 15 expiration of a 35-year-old copyright agreement. Designers Bonnie Erickson and Wayde Harrison -- who also created the famed Muppet Miss Piggy -- say they alone made the Phanatic's character and backstory when they were contracted to create the costume in 1978.

The Phillies argue that the baseball franchise is just as responsible for the success of the mascot as the puppet-making pair.
