本輯以「好行為」作主題，用一個個石仔淘氣小故事，讓孩子在成長中建立正確的好行為，讓孩子與家長一邊閱讀，一邊學懂人生大小道理。/ 這一輯我設計了一個新的角色，阿里。他是主角石仔班上的插班生，他跟其他小朋友的外貌並不一樣，有大大的眼睛，黝黑的皮膚和捲曲的頭髮。

This is the 3rd series of "The Story Of playful Kids". A new character, "Ali" is introduced in this series. Just like what I did for the main characters before, I also designed the new character "Ali"  this time. Ali was a boy with big eyes,curly hair and tanned skin. It made him different form the other kids and everyone was curious about him.
