This is seriously just an animation of Sans's idle animation using costumes and frames. I intend to implement it into my 'Pacifist Sans Battle' somehow. If you want to use it, ask for permission. If I do give you permission, credit me. Feel free to look inside and see the scripts/sprites. However, you're not allowed to just secretly slip it into your backpack and drag it into something else. Yet again, if you're going to use it; ask me.
It's a pretty long process, making this. First of all, I had to find a high-quality gif of Sans's idle animation (faithfully, the UT wiki has it) and then download it, insert the gif into a "gif-to-frame splitter" and download each frame individually, in which then I insert the first frame into the sprites area, and add the remaining frames into the costume tab. Stupidly enough though, I renamed each frame to "Sans1, Sans2" et cetera. However, it Scratch doesn't care about numbering and systematic ordering, so then I have to drag each and every frame into their respective places for who knows how long and finally. I've got that all fixed together. Now I need to make the script, that uses Switch Costume blocks, variables and frame blocks and finding how many fps it need to look like the original animation, and there. It wasn't fun at all, but it was worth it in the end, I guess? Just to let you know how how stupidly tiring it was, there are about 13 frames in that gif, each take about 5-15 seconds just to find where they are, and even longer to drag it across whilst scrolling. Most of the time, it doesn't even go into the place the cursor was directing-it was usually 1 or 2 spaces below.
