Metal Slug 3 (Kawaks) ripping help

[TheGuy33]

I finished the tree first sprites of the giant eels but there is missing a tile in the third sprite. I tried reusing some tiles of the sprite 1 and 2 but it doesn't work. Here is the download link of the sprites (need gimp) https://www.mediafire.com/?a066bns5hsxb9p5 as you can see, there is missing a part of the rope to the right in the third sprite. Is that normal?
