The small Pikmin policy and AR watermark
Okay, so we established that small Pikmin are required to make the gifs so that the animations are shown efficiently. However, there are MANY sizes of Pikmin (I think five) and chances are that the tiniest Pikmin size may not be used, as well as we may not have a consistent size for every gif. If that's going to be the case, I suggest that any of the possible two small size could still be used. The main priority is to make sure the Pikmin's whole model fits within the required gif proportions.
Also, one of the recent updates added an AR watermark when viewing a Pikmin's model. There's no way to remove it in the game, so from now on we may need to make the gifs this way and redo the previous ones, or if possible, edit out the watermark.
Making a list of which decor sets that are "Certified small" (+ AR watermark potentially)
I thought about keeping track if which decor sets have all small Pikmin gifs, so that they do not need reworking anymore.
