>>31529187It's not just a skit, Pomu basically confirmed that she's a shapeshifter in her debut stream even before eldrith horror Pomu 1st appeared on screen. However, this would seriously put her down because this would imply that she wasn't interdimensional, but one person with different aspects on one plain of existance. I also doubt that Pomura Inpuff originates in another dimension, which would be yet another Pomu. You could also consider the act of pomufication which is basically her taking over the minds and bodies of others to turn them into Pomus.
On top of that, she can do the hand thing.
