Sloths are mammals, someone would say not very nice and not very fast mammals, but in Ústí, we have a very special sloth. His name is Ondra and he is the mascot of ESN Usti. He loves to hang out with people even more than he loves his after-lunch-nap, so you are more then welcome to visit the office of ESN Usti and cuddle him a bit, but your task is to find the real sloth hanging in the tree branches in the Zoo of Ústí nad Labem. Upload a selfie as a prove that he didn´t run away from you...oh, wait, sloths don´t run, so it should be pretty easy.
Check the official page of the ZOO for opening hours and entrance fee.
