Thunderbird stepped on the first fence and reduced it to matchwood. She bulldozed through the second without a pause.Paulo dropped the milk bottle and gave chase.Thunderbird walked up the grassy bank. Li ran after her. She was amazed at how long the animal's stride was. She looked like she was going for a gentle amble, but she really covered the ground quickly.Li hurdled over the remains of the fence; then she had an idea. She stopped and picked up a piece of splintered wood from one of the destroyed fences and threw it at Thunderbird. Maybe she would stop for a rematch of their game.The elephant didn't take any notice. She had spied a large body of water and was heading for that.Paulo caught up with Li. 'She's determined,' panted Li. 'Do you think she'll come to any harm?''She can probably get in but she won't be able to get out. And I don't think the cleaning chemicals will do her any good if she drinks them. She might panic if she gets any in her eyes, particularly if she finds she can't get out.'Ahead, Thunderbird towered above them, a black silhouette like the mouth of a huge tunnel.
