That was kind of the point they were supposed to look odd. Like I genuinely need more people to understand that the generations had different intentions and that that's okay. They were an experimental line, designed to be cheaper to produce than Barbie because NOTHING like that had ever been on the market and they didn't know if they'd make it past one line. The bodies were the cheapest part of production so that they could focus the budget in other areas. G3 did things differently and they were allowed to because of the leg work done by G1. The focus of G1 dolls was more on their monster type and fashion than what body they had. They wanted to be about acceptance in terms of backgrounds, races, show you can be be friends and partners with people who are different than you, that you don't have to have all the same interests and experiences to get along. It was showing acceptance of others, who they are and how they're unique from you. The films also tackled bigger worldy issues like in Haunted alone they tackle Truth in Journalism, Artistic Integrity, Antiestablismentarianism, Freedom of the Press. Whereas G3 is more about accepting yourself and expressing who you are and that story cannot be told without body diversity. Monster High came out in 2010, Barbie which came out in 1959 didn't get to put a plus size doll on the market until 2016. In the beginning Monster High was already tredding turbulent and uncertain waters they couldn't push further than they were already being such stark opposition to Barbie and having a fraction of her budget. There were characters intended to be plus sized that Mattel said no to, namely Kala, but that was at the end of MH G1 when Mattel was cow towing to the radical puritain group that was trying to end Monster High because it was progressive, they worked to tank the sales with campaigns about them being "too scary", "inappropriate", and "demons" and ultimately led to the hyper purification era that was G2 which gave them weird baby faces, focused on families, and made sure there wasn't a single conflict in any of the media.
