I don't think they know Pui Pui. Yakon was treated like a well known name, Pocus was a scrub. Scrub or not I think he's still over Kaioshin and Kibito. They seem to revere Babidi's crew for some reason.
When did he show high durability? I thought him surviving at Buu was just because Buu was toying. Seriously, that morbid obese had a kids' smile in his face all the damn time when he was buttraping .
