Becky: The self-proclaimed friend of Cosmi. Cosmi considers her more of a nuisance rather than a friend, considering her obsession to be with him (and pulling pranks on him). She looks similar to Cosmi, but with white skin, blonde jelly-like hair with two snail-like eyes on top (which might mean that her hair is alive as well), a red dress, red boots, a red lady hat and white pants under her dress. She can teleport with a special item. But in the end, she becomes egotistical and demands that everyone should love her.
Mumphy: He is quite the lovely baby of his family, and hasn't left his planet until now. His nickname is the "Ball of fire", which fits his appearance well. He is a robe-clad ball with eyes and a mouth, with pink skin colour and a feather on top. He is quite literally a hothead considering his special item that causes Volcanic Eruptions. In the end, his mother reveals that he is adopted, and shows him a picture of his real mother.
Baron von Proptop: A vagabond of all trades, he travels from world to world to see new life and new civilisations but collapses from exhaustion when reaching Earth. He is saved by a friendly nun, and taken care of by her. He finds out that they suffer from an economical crisis so Proptop decides to thank the nun by winning the contest and giving the prize money to them. He wears a tall French-polis hat, with a propeller on top, a red scard, goggles, green-jumpsuit with large sleeves etc. His special item causes everyone to tie themself up and drop coins. In the end, he wins and returns to the nuns, leaving the money to them and continuing his travels without having them see him. The nun hears his propeller for the last time...
Princess Cleo: A princess from her own world. She has never had a boyfriend and enters all kinds of competitions to raise her fame. Finally she enters the Michief tests to try and raise her fame again. She looks like a mermaid with pink fish skin on her tail, pink hair, a very oddly shaped crown, a white trenchcoat and a human face. She can summon a UFO whenever she wants. In the end, she finds true happiness from witnessing Earth's vast oceans, and decides to spend her entire life in the sea.
Magnetron: A genius in mechanics. He creates a large machine, which he operates called "Magnetron" for the contest. He himself is a small green blob with only one eye, a cat-like mouth and a shell on top of his head. His robot has horns, goggles, a large clunky blue body, magnets for hands and small legs, he can use a special item to drag in every coin for a time-limit. In the end, his success leads to the mass-production of his robots, and he becomes wealthy.
