So I was scrolling through the Spring Fest Pet design contest when I noticed someone has a pet they "designed" which happens to look almost exactly like a design I did last spring fest. It's the same species and almost all the colors are the exact same, all they did was change the name and a few colors. I don't want to call this user out because it could genuinely be their design, but it just looks a little too suspicious. How would I go about reporting this user?

I believe I have found what you are talking about. 8 of the hex codes are exactly the same. I have reported their post.

Thank you for reporting it! I'm glad you saw the similarities as well, I'm probably going to contact Krin about it. After looking at their post again, another one of their pets looks very similar to a pet I did last year and changed the species for this year. This really concerns me that they may be doing this to other user's designs.
