The Kids are technically the only characters to appear in the game before the 1980s characters were introduced.
Virtually nothing is known about them, or how they ended up in Candyland.
History
In every version of the game, there are a group of children that go through Candyland. In the earliest versions of the game, it was a realistically drawn boy and girl, both caucasian.
In the 1980s to 1990s versions, they are more cartoon-like and appear to be twins, both blonde with blue eyes.
In the 2002 version, there are four children, one African American and another Asian. However, it woul appear the blonde twins are still amung the group, although they appear different in terms of clothing, height, facial proportions, and hairstyle.
