BEARS IN SPACE!!
Too big for humans, great for fish
Your basic bear space helmet. Wear this and you won’t suffocate in the vacuum of space. It is too big for humans too wear, but it might make a nice fish bowl.
In 3801 John T. Bearman, a wild bear cleverly disguised as a human scientist, invented the bear space helmet so that his people might take to the skies and take over.
