Mesh cat avatar. has tons of freebie mods available on the marketplace. Just search "bladencat" and sort by price.
Mesh Shark Anthro avatar. also has a few free mods floating around the marketplace.
A good pair of unrigged modifiable glasses. initially styled to be minions themed but can easily be changed to not-that. I tinted mine dark grey and you can't even tell.
A simple tail with two thicknesses. unfortunately is not standalone as it requires outside animations to work properly, but still definitely useful.
Punk Cuff Bracelets
Cute chibi wings
Long tail deformer, for if you ever wished your bento tail was longer than it is.
RP Titler
Rainbow deer eyes
