The Atlantean Beehive is a great source of useful gifts and bonuses. You'll find it at the beginning of the Daily Adventure.
Buy some Nectar from the Trader and give it to the bees. You can buy up to 3x Nectars on each Daily Island.
Open the Beehive and press the Start button. The Bees will get the Nectar and give you a reward. The gift will be randomly chosen among the items in the honeycombs.
