Rubber Kass is a friendly 7 foot tall Rito from the game The Legend of Zelda Breath of the Wild. He's a traveling musician now living with the one who blew him up. He's calm and kindhearted, always ready to make music and sing a song to relax to. As a magic inflatable he can use magic to create a magical zipper to allow the person to wear him like a rubber suit, padded on the inside.
Kass as a rubber inflatable is also indestructable and made of a soft rubber.
