Wally West commands Green Lantern Hal Jordan's ring to return them to normal. Hal discovers that the meteorite has given Rex the Wonder Dog the ability to speak, along with some mental abilities.
Wally quickly scours Africa and discovers the hidden Gorilla City. The heroes are joined by Bobo. They are attacked by Grodd's army, but Rex and Bobo succeed in reducing Grodd to a normal gorilla.
