Description
While everything in the universe is going faster and faster, this sloth is lazing around without any care. It doesn't like to be hurried, but can give good campaign rewards if you just give it enough time (10% bonus per hour in one of its bonus campaigns, so 120% bonus for 12h campaigns).

It is also highly efficient in converting food to growth and gets twice as much growth from food than other pets. The total campaign bonus needed for evo is calculated with bonus% * hours. So a one hour item/multi/food campaign gives 10% and 12 hours give 1440%.
