Surprisingly good berry gatherer. Similar to a Trike in effectiveness but much faster and more mobile. At least on ASA, they also gather rare flowers from normal bushes! Even a low level Giganto should get you 100+ rare flowers in only a few minutes, but make sure to empty its inventory of excess berries every so often and pump up that weight stat. I have a low level Giganto and he gets me enough rare flowers for my beehives so that I'll never need to raid beaver dams or go to the swamp for flowers again!
