This is the 1999 Eucalyptus koala bear Ty Beanie Baby. It was born April 28, 1999. It is long retired. It is mottled gray with pale tan underbelly.
All my beanie babies are authentic, purchased from Hallmark stores and undisplayed and unplayed with. They have been stored in Space Bags for years. All tags are intact. They were purchased in Canada and have the required bilingual tags.
