They are farming berries with the key "C" fiber with rightcklick and wood/tatch with leftclick

Very powerful fighters, harvesters, and lovers. That last one was a joke cause they will kill everything you own without remorse.

This thing is a harvesting god when you tame it. It collects wood, thatch, berries and fiber at insane rates (and you can upgrade its gather rates similar to the moschops)

When tamed, it's primary use is to tickle enemies. Tickling enemies immobilises them for 20 seconds due to hysterical laughter.

RMB will gather slightly more raw meat then hide off of enemies. LMB gathers a more even amount of each. C button will only gather the hide
