The 2016 Olympics has already gotten off to an interesting start, with polluted water and exorbitant phone bills. The most recent problem is a collection of giant rodents known as capybaras who are overrunning the Olympic golf course.

This issue was not exactly unexpected. According to Deadspin, the International Olympic Committee (IOC) was aware of the capybara population before this year's games. “There are about 30-40 of them inside the course perimeter, but they live here and we play golf here, we co-exist,” Mark Johnson, the director of international agronomy for the PGA, tour told The National Post. To combat this, the IOC assigned the course five handlers to wrangle the animals if they got too close to the golfers.

Unfortunately, since the golf course is technically their home, the capybaras are not sitting this event out. The 150-pound animals have already been seen napping in the sand pit traps and cruising across the course.
