It forms most of the creature's upper body. * Central Eye: A large vertical eye sits in the middle of its face. It has a circular pupil surrounded by several layers, allowing it to detect movement. * Multiple Small Eyes: Several tiny eyes or sensory organs are arranged around its central eye, giving it an almost spider-like appearance. * Side Plates: Two large, pointed markings or armored plates sit on either side of its face, resembling protective facial armor. * Lower Mouth: Its mouth consists of a large rounded insect-like jaw with six oval openings containing sharp, interlocking teeth. * Mandibles: Two curved lower jaw structures surround its mouth, helping it grip, crush, and tear prey. ### Biological Features Its head is protected by a tough, egg-like outer shell.

Humans, elves, beastfolk, magical creatures, spirits, and intelligent monsters live throughout the kingdom. Magic is used for almost everything, from transportation and cooking to construction, combat, healing, and everyday convenience. However, the world is also filled with dangerous forests, ancient ruins, dungeons, magical beasts, and mysterious locations such as the legendary Fountain of Evolution. ### 🏫 1.

The fountain possesses the ability to influence the evolution of living creatures, particularly magical plants. Its water can awaken dormant abilities, change physical forms, and produce extraordinary mutations. ### Why It Is Important * It is connected to ancient nature magic. * Magical plants grow unusually powerful near it. * Certain rare creatures are attracted to its energy. * Its existence is known to the academy's highest authorities. * Its true origins remain unknown. Rosetta and the Hoodie Wizard have been assigned to protect it. Rosetta handles defensive magic and barriers, while the Hoodie Wizard provides ranged magical attacks.

Main Character Dynamics The story revolves around three important characters connected to the Fountain of Evolution. — Cotton Planet A reincarnated magical plant that begins as a tiny cotton creature. Cannot speak in plant forms and communicates through expressions and leaf movements. Eventually gains humanoid forms through evolution. The Hoodie Wizard A human student who specializes in magical projectile wands. Always wears a hoodie and goggles, hides his face, and is a terrible broom rider.

A selfish, bratty diva who considers herself extremely important. Specializes in defensive magic and is determined to protect the Fountain of Evolution.

One episode might involve students attending ordinary magic classes, another might feature an aerial broom race, and another could involve a dangerous dungeon expedition. The comedy comes from the characters' personalities and the absurd situations they find themselves in. Meanwhile, the mystery surrounding the Fountain of Evolution gradually reveals a much bigger story. The central concept: A reincarnated little plant enters a world of magic, magical academies, flying brooms, monsters, and bizarre humans. Its journey from a tiny cotton creature to an extraordinary evolved being becomes the center of an increasingly chaotic adventure.
