Magic Cat Academy is a series of short browser games created as Google Doodles for Halloween which were released every four years.
[5] Momo fights in five stages, each at a deeper level, against ghosts and possessed animals such as an immortal jellyfish, a school of bogues, a vampire squid and an anglerfish.
Momo also meets a new aquatic sailor cat friend named Captain Sugar[5] and reaches the final stage, which begins at an underwater fissure haunted by Marshmallow.
In the process, Momo experiences various natural phenomena that take place in the atmosphere being possessed by the ghosts such as a giant golden-crowned flying fox, polar stratospheric clouds, red sprites and constellations.
Before the final stage, Momo confronts Marshmallow and makes him spit out the purple star, which proceeds to enter the sun and turn it into an evil threat.
[7] The game's development involved multiple rejected concepts including elaborate symbols to draw and additional boss enemies.
[8] The characters of Momo and Sugar were based on real-life cats belonging to the game's art designer Juliana Chen.
