Fairy Tail

Synopsis

While returning home from Clover, the starving Fairy Tail wizards stumble upon a deserted village with freshly prepared meals lying about. Erza suspects something amiss and sends the others to find mushrooms in the nearby forest, resulting in giant mushrooms sprouting from Natsu, Gray, and Happy's heads after the wizards eat them. Meanwhile, Erza and Makarov discover a magic circle that transforms everything in the village into giant monsters, which the wizards attempt to eat, only to find them inedible. As they are cornered by the monsters, Makarov lifts the spell and frees the villagers trapped inside the monsters.
