Rosie and Julian, siblings from Canada, travel to London where they put on their deerstalker hats and unravel a mystery. They're provided with clues about Big Ben's shape and then have to find the building. Both kids are also really impressed by the double-decker buses.

The kids now look for "The London Eye," with the hint that it is something that people can ride on. Once they find it, they go to take a look at the Tower Bridge.

Rosie and Julian are in Hawaii discovering land formed from red-hot molten lava that erupted from the center of the earth. With the help of friendly volcano expert Ken and his friend Terri, they learn about a volcano that is taller than Mount Everest, and about Pele, the goddess of fire.

The travel kids visit a town almost completely covered by volcanic rock some twenty years before. There’s not a great deal left of it for them to see! They walk out onto the glassy and slippery surface of the lava flow, where volcano expert Ken takes a sample of some liquid rock to measure the temperature. It’s super hot, and Julian makes the excellent decision to keep his hands well clear!

Trevhon and Tristan, two Canadian brothers, travel to New Zealand where they learn about Māori customs, religion, along with a stick game. The highlight of this segment is Te Puia, a Māori cultural center.

TJ and Tristan eat corn on the cob that's been cooked in a thermal pool and participate in a haka dance.
