Tried every piece of gum

Discovered Morgan's Dying Words

Used a dollar bill to try to buy every drink in the Grog Machine

Did the dance of the hybrid fruit

Read every gravestone

Opened the Crossroads

Bound Guybrush's spirit to his body

Completed the Diet of the Senses

Witnessed Morgan's Final Fate

Found out what Morgan treasures above all else

Defeated LeChuck
