My best guess is that it's some special transportation mode and the sentence belongs to a list 'He takes the train on Monday. He takes the giraffes on Tuesday. He takes the bus on Wednesday.' What I don't get is why he needs more than one. Do they have different routes and he has to change from giraffe no. 13 to no. 42?
For Denmark the giraffe/zoo item is very loaded. I would never dared to put this in a course. http://www.bbc.com/news/science-environment-26118748
