You need to find ten of Herman’s Notes during The Lair of LeChuck Tall Tale. While finding the notes is unnecessary to complete the Tall Tale, they are required to read so you can complete every commendation and earn the LeChuck’s Portrait trinket.
You can find all ten when you step foot on Monkey Island. However, you will need to locate the key for two of them that are locked away.
Banana peels mark each Herman’s Note location, so look for those during your search!
'Cease Fire!,' by Herman Toothrot
You can find the ‘Cease Fire!’ note in the Stockade at the crater. It is sitting on the table next to Herman’s book of recipes. You’ll need to find the Stockade Key to open the Stockade. You can find the key under the white rocks in the flooded crater or in the furniture above the crater.
