I have never seen these at WDW. For my birthday trip to DL a couple of years ago, DH got me one at the restaurant by PoC. The one I had had a lanyard style strap, the lid was Mickey's sorcerer hat, and inside was a birthday pin, and a mickey sorcerer keychain. The fun continued all day as when a CM would spot the bucket they would wish me a happy Birthday. The best one was Tarzan telling me happy birthday from high atop his golden elephant in the parade. I absentminded signed thank you, and he nearly fell off the elephant signing back to me! a fun experience, for sure the buckets are easier for the CM's to spot than the birthday pins!
