The parents' guide to what's in this movie.

Educational Value

Kids learn about biodiversity alongside the characters as they explore the ocean's wonders. Sea turtles talk about migration, currents, and magnetic receptors that help them with direction as they swim miles from their homes. A parrot fish shows his new friends how he makes sand and cleans algae from reefs. The characters also discuss how introducing non-native things (such as human trash, for instance) negatively affects their habitats.

Positive Messages

Four friends embark on adventures that teach them about ocean habitats and environmental concerns that threaten sea residents. The experience teaches them that although they're all unique, they share a common home in the ocean and a common goal to protect its integrity. Also strong themes about making positive changes -- even small ones -- to affect bigger improvements. Excellent examples of friendship and respect for diversity.

Positive Role Models & Representations

The Reeftown Rangers are inquisitive, adventurous, and empathetic. They help others when they can, and they appreciate the diversity of the ocean's inhabitants both for curiosity and for the fact that it takes all kinds of life to keep the sea a balanced ecosystem.

Violence & Scariness
Sexy Stuff

This special accompanies the TV series Splash and Bubbles.

What parents need to know

Parents need to know that One Big Ocean stars the characters from the preschool series Splash and Bubbles in an adventure that takes them beyond their home and into the open ocean. The story excels at teaching kids about marine life, biodiversity, habitats, and scientific concepts such as migration and instinct as it entertains with the characters' experiences. As Splash and his pals make new friends along the way, they come to realize that there's more that unites them with their far-off ocean neighbors than separates them. This creates a sense of unity and inspires them to action to care for their shared underwater home. Strong environmental messages translate to the human world, and kids see the harmful effects of litter on the marine creatures and hear about how fluctuations in ocean temperatures threaten delicate ecosystems. This musical adventure is a lot of fun for youngsters and can inspire some good conversations afterward.

What's the story?

In ONE BIG OCEAN, Splash (voiced by John Tartaglia) is yearning for an epic adventure somewhere far from home, but his pals Bubbles (Leslie Carrara), Ripple (Aymee Garcia), and Dunk (Raymond Carr) fear that visiting new places will tempt their best friend to leave Reeftown in search of bluer waters. They set out with Splash to follow a friendly sea turtle, but they're mindful not to let Splash get too excited about the new places he sees. Even so, their journey teaches them all kinds of interesting things about the ocean home they share with many other creatures and how even the smallest of gestures can affect their sea community as a whole.

Is it any good?

This musical underwater venture teaches kids important lessons about marine life, ecosystems, and the responsibilities everyone has to their respective larger communities. As Splash and his friends ride ocean currents to new places and new friends, they discover that even though they're far from home, they have much in common with all kinds of sea dwellers. A shared sense of purpose emerges, inspiring the characters to look for ways to make small changes that will have a big impact on the ocean -- and its residents -- on the whole.

Of course, educational content is only as good as its presentation, and getting kids to tune in for something for learning purposes can be a trick. Luckily One Big Ocean is more of the same kid-friendly, engaging action that viewers have come to expect from the Splash and Bubbles crew, with similar threads of friendship and diversity throughout. Fun music, unique characters, and vibrant animation make this an excellent choice for preschoolers.
