Building a hoe... by that time I have enough iron to do it, why must I make it with wood?
Creating a sword....I only use iron and diamond swords...no wood.
Monster Hunter.... Make it be at least 5-10 hostile Mobs(Not sure if it works with nether)
Also two more achievements(For now...with the Monster Hunter.) Monster Slayer: (Depending on if he makes it 5 or 10...if he changes that...) 25 Mobs or 50 mobs.
Monster Extermination: 100-150 mobs
Ghast Slain: Slay a ghast (Can be gained after Monster Hunter.)
