From the bestselling author of the BEETLE BOY books comes a picture book to appeal to younger beetle fans everywhere! Deep in the rainforest, Buster and Rex are rhinoceros beetles carrying a banana back to the beetle tree.

Then, when danger arrives, can Buster live up to the stories he's told, or is it up to Rex to save the day?
