Late to School Goblins

Very clever! It reminds me of a book I read by Brandon Mull, where he had creatures called Nipsies. The Nipsies are tiny little fairy folk that hide in the house walls and underground.They help build and clean things without anyone seeing them (kind of like Elf on the shelf where he does things overnight) and also have a knack for treasure. There were also evil/cursed Nipsies that remind me of your goblins. I think it’s so fun to make imaginative stories like this.
