The story of this two-series-long collectible toy series from Magic Box International (the same people who brought you Gogo's Crazy Bones) is that when a three-pointed star touches an object, it turns into a Star Monster that resembles whatever object it touched; for example, if a three-pointed star touches a lamp, the resulting Star Monster will have a personality related to the lamp.
The environment a Star Monster lands in also affects it; each Star Monster has an elemental family it belongs to (seven families are known to exist). The Star Monsters can also evolve and have evolved versions of themselves that can be collected; however, only a few of them have been known to have evolutionary stages beyond the first one.
Three-pointed stars landed in this page and turned into the following tropes:
- Aardvark Trunks: Hanako has a long snout due to an anteater hitting it with its snout.
- Amazing Technicolor Population: Every Star Monster comes in four colors, making them look rather colorful.
- Animate Inanimate Object: Some of the Star Monsters formed from being exposed to inanimate objects, causing them to look like whatever inanimate object they touched.
- Anthropomorphic Food:
- Due to landing on a corn cob, Mazz looks like corn on the cob.
- Lolin looks like a popsicle. He's not enthused by people licking him, until he evolves into Linguer and gets horns.
- Big Eater: Kiba has a big appetite.
- Bilingual Bonus: Tako resembles an octopus due to landing in an aquarium. Its name means "octopus" in Japanese.
- Cock-a-Doodle Dawn: Implied, or lightly referenced. Kikiro, a rooster, has it in its bio that it's the first to get up in the morning and call the others to play.
- Conjoined Eyes: Paiku, Golo, and Guru have them.
- Cyclops: Belbo, Hanne, Xivu, and Guija have a mouth, but only one eye. In Hanne's case, it's because it landed on a camera case. In Xivu's case, it's because it landed on a megaphone, the round shape of the horn-like speaker obviously being where its eye is. Guija came from a guitar, and its eye is mean to be the hole in a guitar.
- Elemental Powers: The Star Monsters are classified into families representing certain elements. Plant, water, earth, air, ice, sound, and shadow families are known to exist. The last three of those families were introduced in Series 2.
- Elemental Rock-Paper-Scissors: Averted, oddly enough. None of the elements used in the series are given weaknesses against each other.
- Evolutionary Levels: A few Star Monsters have one or two possible evolutions once you diverge from the original one. The sole exception is Rok, who has three evolutions instead.
- Eye on a Stalk:
- Nun has them. It landed in an optician's building.
- Pipo, quite literally; she landed on a sunflower and has three shoots with an eye on each.
- Filmon has them. It missed a red crab as it was falling, so the eyes on a stalk are to telegraph its crustacean shape.
- Faceless Eye: Siruos, Skimuz, and Nanor have one. Siuros's bio speculates that it might have fallen into a pipe, hence its weird eye and pipe-like head and neck shape. Skimuz collided with a lighthouse, while Nanor landed between two snakes' nests and peeks out over the water, its body shape giving it the appearance of a periscope.
- Fast as Lightning: Implied. While Kyu is a plant elemental, its bio says that it spent a few days in an electricity plant, it plays games with fast movements, and its bio is capped off with an electricity pun ("Shocking!").
- Funnel-Mouthed Cephalopod: Tako, an octopus-like Star Monster, has a funnel mouth.
- Good Colors, Evil Colors: It's heavily implied that the Shadow Star Monsters are antagonistic, and among the giveaways are that the Shadow family's characters only come in black, whereas the Star Monsters from other families can come in four different colors.
- Graceful in Their Element:
- Rinen, an air-elemental bird Star Monster, is better at flying than at moving on the ground.
- Polin, a penguin who is a water elemental, is an "arrow under water" compared to walking.
- Heavy Sleeper: Michu is a heavy sleeper due to landing on the branches of a eucalyptus tree (eucalyptus leaves have a scent that can help you sleep).
- Heli-Critter: The petals on Oray's head look like a propeller. Oray tries to use them to fly, to no avail.
- Irony: Ichi, which formed in the hearted of the jungle, is scared of all exotic animals.
- Jack of All Stats: Rokton has six points in all its stats (exploration, balance, and power).
- Mushroom Man: Golo looks like a horned mushroom, due to landing on a toadstool.
- Mix-and-Match Critters: Tokki looks like a snake with rabbit ears. Its bio rationalizes that if it's a mixture of those species, "[i]t could only be a Star Monster!"
- Painting the Frost on Windows: Not really, but Star Monsters think Klun creates clouds.
- Palette Swap: Every Star Monster besides those in the Shadow family are available in four colors.
- Pie-Eyed: Numerous Star Monsters have pie-shaped pupils, such as Ramu, Hanako, Minnor, Muzino, Yaggu, Vibro, Foxiju, and Mec.
- Punny Name: Connor landed on a traffic cone and resembles one as a result. Its name is supposed to sound similar to "cone".
- Tooth Strip: Multiple Star Monsters have undivided teeth.
- Vitriolic Best Buds: According to the former's bio, Taro and Dingbo argue but play together all the time. Taro came from a bottle while Dingbo came from a corkscrew opener.
