This takes place during BFDIA 6.
The contestants are unable to eliminate Puffball as she can float and resist the Sender Scooper and the Lasers, but N drops in and cuts Puffball in half. N says things need to be fair, so he vaporizes Dream Island, destroying it. N tells the contestants to participate in a final challenge. It is a fight to destruction, with N thrown in.
N easily defeats the contestants, and they are permanently sent to TLC forever!
"There are zero contestants." said N.
