Fixes Tom description

[Henri215]

What Does This PR Do

Tom now uses his custom description instead of generic mouse one. Removed icon_state for gray mouse since its already set.

Why It's Good For The Game

Tom should be using his custom description, not a generic one.

Testing

• Took a look into other mouses icons and descriptions, all look good.
