Zoos, underfunded, decide to run secret betting rings where modified alpacas are raced on zip lines. The alpacas are also used in the transportation of goods.
Pictured here are the 3 leading zip line, race Alpacas of Rilao. Brainpaca is the finicky-speed demon. 3 Pink is very attuned with his zip line and knows the proper moment when to weave and turn. Marakihau is the crowd favorite, but has lagged behind lately due to a recent snout injury.
