I've contributed to making a world/walkthrough earning you all achievements really easy. You can check out the walkthrough on the following link.

The achievements are grouped per update, although if you are somewhat familiar with the game, just hop into the world and do the achievements without the help of a text guide. Please let me know if you need any help.

Change the difficulty to peaceful and just hang out underwater for 2 min and the achievement unlocks
