Kingdom Hearts
In Kingdom Hearts, they steal an artificial heart from Dr. Finkelstein to give to Oogie. They are soon captured, however, without the heart. After their battle, they reluctantly reveal tips on how to defeat Oogie. It is assumed they leave the mansion afterwards, since they are seen in Kingdom Hearts II.

Kingdom Hearts 358/2 Days
The mischevious trio appears again in Kingdom Hearts 358/2 Days, this time playing a trick on Roxas.

Kingdom Hearts II
In Kingdom Hearts II, it is revealed that they became Dr. Finkelstein's assistants. When they go out to play, they come across Maleficent and tell her of Oogie Boogie's fate. Maleficent revives Oogie and gives them control of the Prison Keeper Heartless as a distraction for Sora and company.
 * First Visit

In the second visit, they are blamed for stealing Christmas presents from Santa. In the inevitable chase afterwards, the heroes discover the truth when they tell them about Dr. Finkelstein's Experiment.

 * Strangely, the hands of the children appear to be different color than their skin under their masks. Whether or not they are wearing gloves is unsure.
