I really like collectibles with darker backgrounds, and it shows in my lineup
To break it down further:
The first item in my lineup is a Friday the 13th Candy. None of the Yellow Candies I bought changed, so I ended up trading someone the Pierrot Candy I won from the Halloween event for it. I really like the coloring of this candy, so I'm glad to have it in my lineup.
The second item is a Yellow Candy from Friday the 13th. I actually sold back all of mine because I didn't think to keep one, so I got this one from someone who was giving them away!
The Eerie Star Potion is very pretty. Blue is my favorite color, and this shade of blue is really nice.
I had a Moonlight Egg in the fourth spot for a bit, but I swapped it out today for another Yellow Candy. I got this candy from the Halloween event, and it balances well with the one from Friday the 13th.
My Cobweb Egg was obtained by hunting the site for eggs. It was my favorite egg from the ones available, and I'm glad I was able to get one.
As for the bottom row, it's a star fragment rainbow! I like rainbows and stars, so it's a perfect row of collectibles for me.
