The Magic Tree House 9

Dolphins at Daybreak

by Mary Pope Osborne
The tree house transports the kids to a coral reef somewhere in the South Pacific or Indian ocean where a mini-submarine gives them a tour of the wildlife, including dolphins and giant clams. We’ve marked the story as having debatable time travel since the only certain time travel comes from returning to Frog Creek, Pennsylvania, at the moment of their departure.
— Michael Main
