>>28010042In Super, when a custom starter doesn't have the proper portrait, a blank one is used instead. When an animation needs to be used but the Pokemon doesn't have one, they "dance", not unlike how Sky makes them use their walking animation as a placeholder.
Only used unevolved mons that don't have any split evos so far, but evolving through the scarves seems to work fine. Jigglypuff, who is considered a middle stage in PMD, was able to revert to that form afterwards like normal instead of turning into Igglybuff.
