Girls Night In is the seventeenth episode of the eight season. It was written by Miranda Larson.
Mandy offers to babysit Lily when Helen Flood invites Mrs Chen and Penny over for a girls' night in.
Unfortunately, after painting the walls, Lily throws a cushion onto Mrs Chen's hot curling tongs and starts a fire - and as she has also hidden the front-door keys, no one can get out either!
Meanwhile, the boys [Sam, Steele, Mike and Elvis] have a games night at the Fire Station - which turns out to be a big disaster.
