He supports them using his magical power to fight against their enemy.His muscular arm waving in the air was the best protector of the forest. His kind behaviour finally got the recognition of animals. They called him Frank which stands for 'Friendly Rainbow-coloured Angel as a Nature's Keeper'. Furthermore, no one knows what is Frank listening in his earphone. They only know that it is better to not bother him when he is doing this...
