This is a alternate texture that is optional, but since it is optional you have to enable it yourself. Here are the steps.

Open File Explorer, click Local Disc, & double click the following folders:
1. Program Files (86)
2. Steam
3. steamapps
4. workshop
5. content
6. 105600
7. 2844005618 (This is the Steam Workshop ID)
8. Content
9. Images

Now, the final step is to rename Item_2176 to whatever you want, then rename configfork into Item 2176. The purpose of that is so the game detects Item_2176 as the current Shroomite Digging Claw sprite, so renaming it at all will make the game think nothing has changed since it can't detect it as a sprite.

If you want it to be a spoon again simply do the opposite.
