The bug

The four bottom rows of pixels in the sea pickle texture file are not used by any of the sea pickle models at all, and can be removed from the texture file without changing how sea pickles look.

In addition, the bottom pixel of each "filament" used for underwater sea pickles is rendered entirely within the sea pickle model itself. Removing these from the texture also has no effect on the outward appearances of sea pickles (the differences can only be seen via Spectator mode), and therefore these can be removed without affecting anything as well.

How to fix

Remove all these pixels from the texture file. I've attached a fixed version of this texture file to the ticket - all that needs done to resolve this issue is to replace vanilla's version of the sea pickle texture with the version attached.
