Crab sideways walks in to tell us that there are nearly 4000 species of crab like him coming from far and wide, and living in both the water and on land.

The butterfly fish takes some time out from being good-looking to tell us how he pecks at coral with his long snout for food, and how he uses his good-looks to confuse and camouflage himself.

The sawfish wakes up from his sleep to show us all of the uses for his saw-shaped nose, including catching food, digging and defending himself.

Here, flying around a pond, we meet a newly grown up dragonfly. While she may have spent two years growing up underwater, she's only going to be an adult for two weeks.

The aggressive and pushy lionfish shows us what he's made of and why few fish would dare to mess with them, and to those that would, he's a kitten.

Meet the moth, a voiceless critter that dreams of one day being in the spotlight. She tells us about how she loves the light and flower nectar but it's a shame she doesn't get more attention like her relative, the butterfly.

We meet Goldfish in his tank, where he shows us where he came from and he explains their three month memory and unique ability to see in colour. Goldfish explains they are social animals who love much bigger spaces.

Insulted by the salt left in the garden, this slug begins to tell us how wrong we are about him. With his 25,000 teeth, he eats things like dead leaves, fungus, and dog poo all over the world.

Jellyfish shows us how they catch their prey and fend off predators using their stinging tentacles. Also, they can see their food after they eat it because of their see-through bodies.

Giant Clam explains what they eat that help them to grow from being very tiny clams to giant ones. They also have a very effective defence mechanism that helps them live for up to 100 years.

Ngarritj is a little white corella with a big attitude who flies freely around the Yolngu community of Galiwin'ku visiting everyone and speaking the local language.

The team travel to avalanche country and the French ski town of Tignes in the Alps. Clare and Dougal go skiing in the shadow of the biggest avalanche threat in the mountains and test out the latest survival technology.

Mike, Dougal and Leah are on an epic, rain-soaked journey. The team travel the length of India tracking the monsoon - the world's biggest weather phenomenon, as it passes over the country to the world's wettest place.

Clare, Dougal, Leo and Mike discover the secrets of ice. On a bobsleigh track in the Swiss Alps, Leo learns about the slippery properties of this frozen substance, while Mike explores the devastating power of ice storms.

The team travel 9656km to the country of Chile and the Atacama Desert, officially the driest place in the world. Leo skydives out of a plane to reveal why the air is so dry.

Three schools. Three Australian states. Three missions. In this episode of Project Planet, the journey of our three schools and their quest to become sustainable culminates in three very different ways. From constructing a sustainable oasis, to making a mural with a message, to rapping it out with a song full of purpose, our Waste Warriors have truly made a difference on this beautiful planet.
