☛ Click to cycle through four different images. That is what it appears like at normal size, but at full screen size, it is just a jumble of pixels. Actually, it is just a single image, slightly repositioned in the bitmap editor. Check the costumes inside to confirm it yourself.
ℹ️ This does not work in full screen mode, and apparently not even in normal mode on some devices. Not sure why. In the second costume, the image is shifted one pixel to the right in the editor. In the third, it has been shifted one pixel to the right, and one down. In the fourth, it has been shifted one pixel downwards. However, the bitmap editor has twice the resolution of the normal stage size, so each pixel in the bitmap editor is a quarter of a pixel on the screen at normal stage size. This means that you have to use full screen mode to see all pixels. And it can be used for some fun tricks :) Scratch handles double-resolution bitmap images in a quirky way - instead of setting the color of each pixel to an average of the four subpixels, it simply sets the pixel color to that of the bottom right subpixel. So for example, an image where the bottom right pixels (25% of the pixels) are white but the rest (75% of the pixels) are black, the image will appear white at normal size, but dark gray at full size. For a fun surprise, try applying the whirl or fisheye effect (I recommend values between 0.01 and 3). More subpixel fun here: https://scratch.mit.edu/projects/1257778425/
