Upvoted you, mainly because you echoed my own sentiments about the hippos perfectly. Ever since I first heard about this I thought it was more fascinatingly delightful than anything unfortunate, and in terms of damage, nature itself is full of species collisions, so this is hardly the sky falling. It's also absurdly amusing that the ferociously bloody crime giant Pablo Escobar's single most enduring, still growing material legacy has been this of all things: the small herd of hippos he decided to import one day as a casual, probably barely considered gesture of showing off his wealth.
