Stardew valley where is the spritesheet with the crop-items?

[Barack Obama]

The game uses .XNB files, which means everything can be ripped with a tool called xnbcli 1.0.7:

Edit:
In short:
Extract xnbcli, put your xnb files into the "packed" folder and run unpack.bat
The corresponding images will now appear in the "unpacked" folder.

Edit 2:
I found it. The internal file name is springobjects.xnb
I just submitted it, should be accepted soon.
