藝文進階題的關卡「時空旅人」，為小隊們帶來更具有挑戰的藝文題目。關卡故事的背景是智慧老鐵人痛失愛妻，雖然擁有遺物，但卻四處散落遺失，因此小鐵人們要負責將從古至今、橫跨東西方的音樂和美術知識串連配對，好讓智慧老鐵人得以喚回最珍貴的記憶。
The task DOLL gets team into a further stage of literature & arts challenge. In here, team members should fix all the questions of music and art from the past to present of both Western and Eastern worlds. Then can help the old man of IICC to bring back his memories.
闖關過程中，小隊首先要透過串連相關藝術知識，來取得紙娃娃的衣服，接著將獲得的衣服配對，替紙娃娃穿上後，再將其所屬的時代服裝造型與建築配對，因而得以闖關。關主李其恩是關卡背後的重要推手，最初的發想是來自她最珍貴的童年記憶。李其恩分享， 因為自小就很喜歡紙娃娃，所以最初就從紙娃娃開始構想，由於過去競賽很多關卡都考過各國的傳統服飾，所以關卡特別設計以年代區分，就會做出鑑別度。
In the task, the team will be asked to wear paper doll’s clothes. The clothes will be pair with related architectural style of buildings. And the one who made the task, is the taskmaster Ann Lee.She shared that it was all start from her favorite toy paper doll. Then she designs series of question to accompany with it.
除了有推手，關卡的生成還要有幫手，另一位關主劉品岑是李其恩過去參賽的盟友，兩人合作無間，因為都喜歡智鐵帶來的趣味，所以相約成為關主，劉品岑分享，當上關主後，趣味度不但不曾減少，反而越益增加，但他也說，唯有場佈讓他感到辛苦，不過所有疲憊都會在小隊員們稱讚的時候消失殆盡。
Not only Ann made these, but also another taskmaster Jerry Liu. He and Ann were teammates, they cooperating in a wonderful way, so the task can soon be figured out.Mention to the difference of being a taskmaster and team member, decorating is hard and bored, said Jerry, but it can be pay off if the team members love it.
