Stone Mirth on Earth

Actually, Stone Mirth, a volcanic stone, would like to live up to his name and he would have a reason to be happy because as a Martian stone he has many abilities that earthly stones do not have.

The earthly stones feel more and more helpless as the darkness increases and evil gains more power. Their only hope is Stone Mirth who, with his extraterrestrial abilities, seems to be able to stop the increasing darkness. But as soon as he arrives on Earth, he is overcome by homesickness since the temperature is far too hot for him and this strange nature also seems quite detestable to him. Help Stone Mirth destroy the evil stone and save the earth! Guide him along his path so that he can return to his planet and there prove to the stones of Mars that he is not the failure they think he is, but a hero who takes responsibility for all his actions.
