Specially genetically bred for Rilao, these Alpacas are Speed Junkies. Since 2014, network of ziplines grew ever more now reaching about 55% percent of Rilao archipelago. It is the only infrastructure on the island with 100% approval by all. Winner Alpacas are worshiped and considered a national treasure. There is a whole department at Rilao academy dedicated to designing most aerodynamic capsules and prosthesis for optimal performance.
In past few years there were rumors of ZipLine Race Inc.™ involved in rather nasty revelations about drug smuggling ring among the archipelago islands (and outside)... but spokesperson at ZipLine™ denies any such allegations.
