I need help with finding an animation. I already tried asking on /r/ and got ignored, so I might as well try here.

I need to find the full version of pic related. The artist purged their FurAffinity page several months ago and this preview image is all that's left in the FA archive on the dark net. The artist linked the full animation in the original post's description, but in the archive the URL has been truncated to https://mega.nz/file/R8lADAYT#ucHXx.....uXaenfT5lTcvCE
And no, the post page is not on the wayback machine so I can get the full link from there. Hell, it's probably deleted from Mega anyway.

If anyone has the full animation, please post it here. Or, if there is a way to extrapolate an incomplete Mega key, please show it here.
If it helps, the animation was posted to e621 at https://e621.net/posts/3335817
