This is one of the more enjoyable "100" lists. It also shows a lot of thought that went into designing the list and types of goblins.
You don't get just the "type" of goblin, but a small blurb of explanation is given to assist you in understanding why they are called what they are. I wish they had done the same with the "Dragon type" list.
Some really good examples are the "Cat Skinners - Traditionally garbed in the skin of stray cats" or the "Ghosteye - White eye goblins who practice rituals to summon eldritch abominations" or the "Kilnborn - Goblins created by a forge god, made of clay and
baked in elemental fire."
Admittedly, there are some silly ones included, like the Red Tummy - The bright red tummy of this tribe is like a baboon butt. But then again, we are dealing with goblins...the cockroaches of the bipedal creatures.
