Despite some jazzy special effects achieved with shimmery holographs, this cautionary tale about selfishness and vanity has trouble staying afloat. Rainbow Fish, "the most beautiful fish in the entire ocean," refuses to share his prized iridescent scales--which, indeed, flash and sparkle like prisms as each page is turned. When his greed leaves him without friends or admirers, the lonely fish seeks advice from the wise octopus, who counsels him to give away his beauty and "discover how to be happy."
