This was inspired by a design I saw in a contest, which had a second "hidden" design of runes hidden under another gene. (The design was made by Xiaoyao8.) I thought this was creative, and started trying to design a pet that was several designs in one. Here are my attempts, and of course I'd like to see other people's ideas, too!
All you have to do is take the designs into the generator, and follow the instructions to get the different designs.

First off, my Day to Night Aurleon:


Take this design to the generator, and first switch G3 to carry. This is my "sunset" stage. Then switch G2 to carry, and it will be my "night" stage!
This could also work as a sunrise set of designs, if done the other way around.


My Four Seasons Aeridini:

1. We start in "spring". 2. Switch G1 and M2 to carry. 3. Switch M1 to carry, and G2, M2 and M3 to vis. 4. Switch all to carry, then switch G3 to vis.
Winter's more like "first frost", but I think it's still not bad!

I'd like to see your thoughts and ideas!

I HECKING LOVE THE AURLEON! That's really smart and you nailed the transitions really well, really good color scheme

The Aerdini is a bit subtler and more complicated but It's still really nice

ps. Did the design you see happen to be a Ryori called Area 51 for the BobRoss contest? That was me btw :P

Yes, it was that design! It didn't have a username by it, naturally, so I didn't know whose entry it was. I'll add that to my description.
And thank you, I'm glad you like my designs! :D

Ah very cool! Seems pretty tricky to do. Creative indeed.
