If you want, you can post a picture of your profile photo, so that you can have a secret style, and it'll only take five easy steps!
1. Post your avatar.
2. I'll download it.
3. I'll secret-style it!
4. I'll upload it.
5. You can download the new avatar, and choose it for your profile photo!
That's pretty much how I got my secret-style; I edited my avatar so that it was pink and purple with a bigger tail.
