If you've never seen an optical illusion before, don't feel bad. I'd never seen one either until my human showed me this picture of a little tiny Dutch standing next to a great big giant scooter thing.
Just in case you've never seen a scooter before either, here's a totally humiliating picture of me standing on one. As you can see, there's nothing great big or giant about it.
Now. I was there when my human took that picture of Dutch. And I know, for a fact, that the scooter thing (technical term: Vespa) was not ridiculously huge. Dutch didn't shrink just for the picture either. Apparently that's what an optical illusion is all about - making things look different than they really are.
Optical illusions can also make your head look very big, like in this picture of Lily.
Or give you huge feet and very long legs. Like a labrador.
Optical illusions are pretty cool - but they can also be a little scary. Because they are totally capable of turning a big freaky fish into a GINORMOUS freaky fish that could swallow a pug whole. In one gulp. Without chewing (if fish even chew).
If you're wondering what sort of crazy camera voodoo made all this happen, I think it has something to do with the lens my human used and the way she used it. I kinda wish there was a way to make optical illusions real. Not the freaky giant fish (that would be superscary) but having a pug-sized Dutch would almost be like having a real pug brother.
