The Star Children (singular: Star Child) are seven babies that possess, as Kamek puts it in Yoshi's Island DS, "an extraordinary amount of power." In the game, Bowser travels back in time to steal the stars from these children to take over the universe – the true intentions behind the kidnappings of all the children. However, few of the children captured by the Toadies turned out to be star children.
Baby Mario, Baby Luigi, Baby Peach, Baby DK, Baby Wario, and Baby Bowser were all captured, but Baby Mario and Baby Peach were rescued by the Stork from the initial kidnapping, Baby Luigi hid at the time Bowser and Kamek were checking the babies for stars, Baby Wario was dumped in a cave by a Toady after he threw an enormous temper tantrum, and Baby Bowser enraged Bowser into kicking him out of the castle. It is unknown how exactly Baby DK escaped capture (he most likely hid when the Toadies invaded his house), only shown falling from the sky and landing on Yoshi's back. It is unclear, however, whether the seventh Star Child was born prior to the game's events, or if it was born at the very end of the game. There has been a lot of speculation and debate from fans surrounding this.

Bowser: Still no clue where the stars are?!
Kamek: No, sir. But the crystal clearly says that the seven stars did fall during this time period. And I'm getting a strong reading that they are resting inside the hearts of the babies!
Bowser: And you're absolutely sure that these stars are powerful enough to take over the universe?
Kamek: No doubt about it, sir. The babies are called star children, and they each possess an extraordinary amount of power... And once they're in your royal hands, sir, the world is your oyster. Look into my crystal ball. Any star child will have a star hovering above it.
Bowser: No no no! None of these stupid kids have stars!
