You should change the color counter to 29, then; currently it says eight, which would only be true if you were submitting an individual slime (also transparency counts as a color; is it eight counting transparency or eight plus transparency?).
Indeed 8 colors per slime.
I drew them a moment ago but I thought to post when seeing your slime :b
Looks more like eight colors per slime. 33 colors (counting transparency)?
Week of the slime?
