Glad you found it. However I'm concerned with the layout you describe. It should be 4 rows by 12 columns. In fact all animations are 4 rows (except die animation), for up, left, down and right.
For the fishing animations the rows work as I said above. As for the columns, the first 4 are the throw animation, the next 4 are used when waiting for a fish to bite, and the last 4 are for pulling the fish in.
If you don't have such a spritesheet, then something is wrongly defined in the data files. Let me know so I can help there.
