"What's that car doing?"

At lunchtime Temalisi went out into the bay outside Room 16 and said "What is that car doing in our bay?"  We all watched and found out that Little Tractor's battery had gone flat and it wouldn't start.  "Has it got a battery like our iPads?" asked Tumanako.  "We have to charge them when they go flat," said Marius.  The car battery helped Little Tractor start and off he went to do another job.
