"Doña Rosa needs our help." Rico straightened his feathered body and looked at them with round golden eyes. "I can do this." Eyeing the smoking hole in the ground, he hesitated, then jumped in.

Bicultural siblings Rico, Diego, and Araceli Martinez had hoped to enjoy their spring break exploring virtual reality. However, the fun abruptly ends when their inventor friend Don Toño begins work on a new adventure.

While he is out of town, his wife Doña Rosa has an accident and finds herself trapped in the mysterious shed. Unsure of the risks of entering an unfinished adventure, the kids bravely venture into virtual reality to track him down.

Arriving in the tropical Galápagos Islands, the kids discover that they are now animals, able to communicate with the local wildlife. Penguins, lava lizards, birds, and iguanas join them in searching for the one person - or animal - who can save Doña Rosa. If only they could fly over the island!

At the top of the volcano, a colony of giant tortoises awaits them. Will the mysterious Don Tortuga be able to help them save their beloved neighbor? Or will a technology glitch halt the mission in its tracks?
