Ice Ladder

It’s still frosty in Greendale and the children decide to go sledging. The twins lose control of their sledge and end up on an icy pond. They are in a dangerous situation, particularly when the ice starts to break up. Luckily Pat is on his deliveries and has a long, retractable ladder, which needs to be delivered to Alf. He uses the ladder to crawl across the ice and rescue the children. Alf puts up a notice by the edge of the pond, warning every one of the dangers of broken ice.
