It's the day of the children's picnic in Greendale and Ted Glen has built an ice cream machine for the occasion. When the power cuts out, the ever-inventive Ted tries all kinds of ways to get his machine back in action - even connecting it up to Pat's van! He finally hits on a solution and there are plenty of delicious flavours in time for the picnic, including a special surprise flavour that's not very popular with Pat but is just the thing for Jess!
