When Doki shares Oto and Anabella's bubble-gum blowing pictures online, a Wec friend says it reminds him of the bubbles the worms make in Waitomo, New Zealand. Doki is amazed , why would a worm blow bubbles? With Gabi's own pet worm Lancelot in tow, they set off to find out! In New Zealand, Doki, Gabi, Mundi and Anabella explore a glow-worm cave, while Fico and Oto worm-sit. But Fico decides to take Lancelot 'zorbing' (a hill-rolling sport) and the worm ends up stuck in a kiwi bird's burrow! Will the glow-worms inspire a solution before Lancelot becomes a kiwi snack?
While touring Cape Canaveral, Florida, the Team meets Doki's doppelganger, an astronaut named Duncan. Doki excitedly asks - what does it take to be an astronaut? Duncan gives them the chance to find out! But while getting a taste of astronaut training, Doki is mistaken for Duncan, and mistakenly sent to space! Oto must fly the plane-rocket to rendezvous with this mission gone wrong, to save Doki and safely complete the mission. Doki realizes that he may not have the astronaut knowledge yet - but he does have courage and resourcefulness. And that's a good start!
