Overview: Our challenger this time is Ayatar, Japan resident and Thai influencer. An Ikebukuro, Tokyo, rooftop aquarium is the setting for his harrowing mission. Alongside 8 aquarium keepers he'll have to scoop out a jaw - dropping 500 moon jellyfish one by one in buckets, clean the entire aquarium by hand, and return the jellies safely to their Tokyo rooftop home. With only 5 hours to finish the job, will they be able to succeed?
