—Description of goblins from Strange Notebook
Goblin (ゴブリン Goburin ) is a race of grey-skinned Faeries and among magical creatures who work at Luna Nova Magical Academy as laborers.
Goblins are grey humanoid fairies with a small stature and a large head that has large pointy ears and oval eyes with small brown pupils. They lack a visible nose and have sharp fangs. They appear to be the only magical creatures that are truly capable of speaking human language. So far only male goblins have been seen in the series.
Powers and Abilities
In spite of their small stature, goblins are competent in various jobs such as cooking and cleaning. Some are shown working as janitors while others work as chefs. If they are deprived of magical energy, they become considerably weakened to the point they can't move at all.
In addition of regular grey goblins, there are other variations:
Leaf GoblinA small goblin species around thrice smaller than their cousins featured in anime. They have yellowish green body with brown eyes, legs, and points of their ears, mouth full of sharp teeth, lack of visible nose, and a pair of small horns above their forehead. One that featured in short film wear what appeared to be hoodie made of leaf and a small green hat that ends with twin leaves.
It's seen by Akko as a brownie, Akko caught one and insisted that she and her teammates use it in their Fusion Magic experiment. Sucy felt skeptical with Akko's claim whether it really a brownie due to its goblin-like traits and insisted that it would be best if they use her poisonous mushroom instead. Akko argued this idea and she and Sucy ended up bickering, resulting both "brownie" and the mushroom fell into their fusion potion, resulting it explodes into a horrific mushroom-like abomination with Akko, Lotte, and Sucy trapped on top of its head.
Winged GoblinsWinged Goblins are small, goblin-like creatures that has a long tail which ends resemble arrowhead and a pair of insectoid wings. Much like leaf goblin in the second film, they have a pair of horns above their foreheads. Many of them worked at Luna Nova as laborers.
