This is my 3D designed Space Planter tool. It would be used to grow plants on the ISS while being really water conservative.
First, put the disc into the "mouth" of the creature. Tie a string to each of the ears and dangle them down through the hole in the disc into the lower part of the monster. Fill this lower part with water. Fill the top part with dirt and plant a seed. The plant will actually suck up any water it needs from the two strings dangling into the water, so it is very water-conservative. Also, it looks like a cute monster!
