(Looks better, not perfect though)
(you'd have to redo the samurott sprite entirely to get it better than this)
(I got most the flickering, but there's a little bit left)
(pretty much as good as it gets)
edit 2 onwards:
(fixed belly flashing)
(flickering)
(it looks better, most of the flickering is gone)
(flashing shadow under the mouth)
(fixed the white dots on the back)
(everything except the cutoff should be fixed now)
(fixed Snorlax outline, but it doesn't look that much better)
(removed the flickering, fixed up the shadows)
edit 3:
(flickering back, the tail looks like that from the rip idk how to fix that)
(fixed a shadow flash on the lower back)
(everything was wrong before (
))
(random pixels and shadow under the mouth)
(the slowdown)
(flashing shadows)
