From the Super Mario Wiki
Each Harold has a rotund body and displays a Viking-styled braided beard, with each knit featuring a painting of a sharp triangle that points towards the beard's end. The beard is grown around a small face, consisting of a round bunny snout over a tiny incisor tooth, a small red nose, and minuscule eyes under two bushy brows. A Harold's figure seems upset or maddened, as it characterizes its temper. A Harold also features two distant ears, fastened with blue hair ties as if they were hair ponytails. A splayed bun is on top of a Harold's head, which is also tightened by a blue hair tie.
Unlike many other Snowmad warriors, Harolds remain in one spot. However, they may jump from time to time in an attempt to gain impulse. They attack by throwing Watermelon Fuse Bombs at the Kongs. Donkey Kong can attack a Harold by picking up the bomb and throwing it back at it. When defeated, a Harold screams while falling off-screen. The Kongs can also defeat a Harold by performing a Roll Attack three times or by stomping on it three times.
