Each of the games is based off of characters from many of the shows that kids watch on TV. Each of these characters, from Littlefoot (Land Before Time), to Caillou, to Zoboomafoo and Jay-Jay look, sound and act just like their TV counterparts. Each game depicts their character in the same style as the show (whether it is simplistic cartoon animation or stuffed animals) and really helps the kids identify with the characters they are familiar with.
Not only do the characters look like those from the show but in many (if not all) cases, the games use the same voice actors, sound effects and music.
