I saw this episode of (or TV short for) "We Bare Bears" several years ago as a promo for the show coming to the Cartoon Network. At only a couple minutes while the regular episodes are around eleven minutes, it is certainly different in this regard but no better in terms of content. "We Bare Bears" has never been an interesting show to me, in its for little-kid drawing style, bland stories, and uninteresting premise all around. Maybe I've not seen enough to really judge, but one thing for certain is that the baby bear episodes are always the worst compared to the other ones (which could sometimes be alright) and "Potty Time" is sadly one of the former. Clearly these episodes were designed to be cute, but aren't at least to me and come of as bad attempts to be as such.
"Potty Time" relies upon one unfunny and immature plot thread: the baby bears desperately want people to adopt them, when Panda subtly warns them he has to go to the bathroom. So the three bears are running around looking for a bathroom, and then a sort of crude twist happens at the end that is mildly amusing but at the same time an unfunny use of potty-humor. At two minutes one can't criticize the short too much, but because it is already an uninteresting baby bear episode and also childishly unfunny, I can't really call it very good. I remember finding it somewhat funny the years ago I watched it, but now when looking back I just feel like it was nothing to write home about and sort of a dumb premise to begin with.
