There are hippos in Colombia, thanks to the notorious drug lord Pablo Escobar. BBC News' William Kremer writes that the cocaine trafficker once built himself a zoo filled with exotic wildlife. Following Escobar's death, his animals were relocated across the country — all except the hippos. There had initially only been four, but the creature's numbers have swelled up to 50, and possibly many more have escaped and are now flourishing in Colombia's tropical climate. The article also examines the various attempts that have been made to contend with these "living, breathing metaphors for Escobar's place in Colombia's national psyche."
