Terraria

Note: This requires v1.2.4. Go to the Jungle biome. Enter a bee hive inside one of the underground jungles. Destroy larvae (large bees inside crystallized shells) to make a Queen Bee appear. Note: Some hives have two larvae. If you destroy both at the same time you will end up facing two Queen Bees at the same time. Defeat the Queen Bee to get Honeyed Goggles. Use the Honeyed Goggles to get a Bee mount. Note: You can also summon Queen Bees by crafting Abeeminations by using five Honey Blocks, five Hive Blocks, one Stinger, and one Bottled Honey. Honey Blocks and Hive Blocks can collected from the Bee Hive mini-biome. Destroying Hive Blocks will summon weaker bee enemies that drop Stingers. Bottled Honey is obtained by collecting Honey Blocks and using the empty glass bottles by hand while standing next to the honey. Use the Abeemination is in a Jungle Biome to summon a Queen Bee.

Note: This requires v1.2.4. Get a Golden Fishing Rod from Pirates in the Hardmode Ocean Biome. Either use a Treasure Map or wait for a Pirate Invasion (happens only after the Wall of Flesh is defeated). Get a Truffle Worm in a Mushroom Biome. They appear as small glowing worms and can be captured by quickly dropping down on it while swinging the bug net. Travel to the far east or west oceans and use the Golden Fishing Rod with the Truffle Worm as bait. Duke Fishron should appear and attack.
