Kiko is a mischievous boy who often gets in trouble for hurting animals and destroying plants. One day, he kicks an anthill and his mother apologizes to the dwarf who lives there. The next day, Kiko breaks some lizard eggs and a dwarf punishes him by transforming him into a house lizard. As a lizard, Kiko must kiss the ground before evening and live in the house. His mother names him "House Lizard" and he remains a lizard, living in the house.
