The One-layered Sugar Chest is a blocker in Candy Crush Saga. It is officially introduced, both as appearance and starting configuration, in level 711. However, it makes an unofficial appearance in level 501.
This is one of the few blockers that did not appear in Dreamworld. Following the removal of the toffee tornadoes and the unofficial introduction of UFOs and popcorn in Dreamworld, as well as the release of locked chocolate in level 52, this was the only blocker or element to have never appeared in Dreamworld prior to its removal.
