Tyco released this plush in 1999 as part of Sesame Street's 30th anniversary. This Kermit the Frog plush is unique because it's the only Kermit toy released in a Sesame Street line of toys.
This plush had a badge on its chest which had the Sesame Street 30th Anniversary logo, and Jim Henson's signature on one of its feet. When you press Kermit's stomach, he sings a few lines of "Caribbean Amphibian". His mouth also opens and closes while singing. Hold his mouth down and he hums the song. He also says a few other things, including "Hi, ho! Kermit the Frog here!" and "Ribbit, ribbit!"
