Kumo has a scar on the bridge of his nose btw, and is a fox not a cat.
Wings attach via rare earth magnets (a pouch in the back holds the magnets on the inside) super huge ears and tails on both, Chibity's ears wiggle.
Both heads can "pop the top" as in lift up like a welder's helmet. When Kumo lifts his head in the video you can see a little skin (this only shows when you look up, this small gap also allows for extra cooling) the neck is connected from the ears back, meaning when you lift the head the neck stays under your chin.
Popping the top is great for quick cooling down and for using your vision 100% if needed,. There is nothing worse than a kid running up when your head is off, with this design you can easily pop your head back on if a kid shows up
I make my heads in the pop the top style whenever I can (does not work with all heads)
