How do I replicate the fuzzy effect during the idle animation

[thespongemagic]

I have a very specific question pertaining to making a custom character in SRB2Kart. I was wondering if it's at all possible to recreate the phasing effect you see on the sprites when you're idle. I thought it would be displacing every other vertical column. But when I go to do it, it looks off.

Any tips or suggestions? Thanks.
