Gobsmurfer

A gobsmurfer (its actual title is The Everlasting Gobsmurfer) is a candy similar to a jawbreaker that's supposed to last a really long time when it's being sucked on. It was created by Greedy Smurf in the EMPATH: The Luckiest Smurf story series as an alternative to lollipops. However, he does advise his fellow Smurfs not to go to sleep while having a gobsmurfer in their mouths.
