• Where would wind get her dog when there is no pet store in her world?
• what happend i want to know ! ^,^
• Watch the video closely again. Notice how all things are flipped because it is a mobius strip. Wind is purposely spelt with wonky handwriting so that when flipped it becomes mr.ug. Also notice that all land marks have their names flipped as well as the messages that were left.
To answer your question. The two "halves" of wind's world are actually one long strip. This works on the fact that her world is a mobius strip. So with that knowledge, I would assume that wind and her dog meet up and live happily ever after.
• That was brilliant. Such an entartaining way to show off the properties of mobius loops. Shame about the ending though. Poor Wind, all alone.
• No, she can pass through the linked loops to reach the dog!

• At Vi is hiding the 'n' that Wind wrote when she wrote 'BACK SOON'
• How did the buildings get there if there was no one else on wind's world?
• They must have fallen off after building the buildings.
• So is a mobius strip is an infinite one sided shape?
• It is sort of like the outside edge of a circle. But the strip has thickness, making it 3D.

• Where did Wind get her dog since there was no pound, and where did she get her food since the stores were always closed, and where did she get her water?
• Wind is a triangle, and triangles don't need food or water to survive. They can survive forever without any of those things. As for the dog, it probably fell from another flatland where dogs exist.
• what does 'nom n' life,nom.' mean?
• I thought it meant something like that you're chewing through life in the sense of being in control of it! You can do things like hop through life or breeze through life; it sounds like that.

Also, apparently some people say they're "nomming through life" if they care a lot about eating tasty foods and do it a lot.
