Main characters •
Gajah: A yellow elephant with memory problems who is on a journey to return to his country of origin. He got lost after falling from the sky (possibly from the airship) and crashing in the middle of the Brazilian savanna, where he forms an alliance with the termite colony and befriends Duda. His main function on the journey is to supply the train with water, since he is the only one who can carry water through his trunk. He always wears a
turban that appears to float above his head. •
Duda: An enthusiastic and
bespectacled red vegetarian
anteater who is Gajah's best friend. She is cheerful and somewhat "childish" for her age, as she always speaks in a hyperactive matter. Sometimes, she loses control of her insectivorous cravings and even loses her vegetarian appetite, but she always returns to normal. Duda often likes to
meditate and play the
banjo during her spare time. •
The Termite Queen: The bossy and authoritarian ruler of the termite colony, as well as the owner of the train. She is always giving orders and annoying others, especially to Gajah. However, grumpy she may be, she truly cares about her people (sometimes showing some gratitude towards others) and is determined to find a way to get the colony back to their supposed home planet. •
The Captain: A loyal termite in command, he is the one in charge of the army as well as the safety of the train and the pilots. He often proves to be as arrogant as the Queen, but always obeys her orders. He wears an eye patch and a captain's hat that appears to float above his head, like Gajah's turban. •
Junior: A young, yet very intelligent termite who is the Queen's son. Unlike the rest of the colony, he shows the most knowledge and tends to be well-aware of the earth's natural phenomena as well as the flora and fauna of the continent. He wears a pair of glasses similar to Duda's (but smaller), with a brace headgear around his mouth and a topknot in the style of a nerd. •
Master Vulture: A wise purple vulture who serves as a sort of "spirit guide" by giving Gajah and Duda advices, despite lacking any manners. He usually speaks with a hillbilly accent.
