Groink does not have a harmonious and even semi-developed body. To have just arms baulked onto tiny, droopy and shrunk pecs , big , bloated and herniated belly, small little stickman legs , it is just not an appealing look. Not to anyone but especially someone used to seriously judging a physique.
Groank could learn from the likes of Bobs and Sherief about things such as balance, proportion and separation. Instead he will just attack them and embarrass himself in the process.
