Arthur and the Revenge of Maltazard

In the 1960s, 13-year-old Arthur stays with his grandparents in the holidays. He is befriended with a Maasai-like tribe called the Bogo Matassalai and with the Minimoys, tooth-sized, elfin beings, who all live there in the garden. The Bogo Matassalai grant Arthur a distinction regarding being one with nature, after succeeding in a series of tests, such as hugging a tree for hours, sleeping with a wild animal, and eating grass.

The Bogo Matassalai are capable of transforming a person to a Minimoy. It is only possible every tenth full moon, at midnight. Arthur is about to undergo this procedure, to visit the Minimoys (who are expecting him and preparing a party for him), and especially his beloved Selenia. A spider delivers to Arthur a grain of rice with the message "help", which must come from the Minimoys, and makes it even more important for him to visit them.
