It's Not a Box: Intergalactic Edition
Start with a box. Think outside of it. Transform it into something from a far off world.
First, imagine what something from another world looks like? Is this creature even alive or could it be more machine? Start with a box big enough to climb into. Build a head that fits over yours. Attach flexible arms with grabber claws to manipulate the world around you. Create custom feet for different ways to move.
