These are the MLP:FIM foal characters the Cake Twins, (left to right) Pound Cake and Pumpkin Cake.
 
The infant foals in MLP look too weird with the beady eyes so I gave the foals the eyes older foals and adult ponies have. Plus, these type of eyes make them cuter. And it’s more realistic since every mammal has pupils so that applies to ponies too. I also gave them visible hooves since equine don’t have hooves covered in fur and plus, the show makes it look like they don’t have hooves so here you go. Pumpkin Cake has the more Unicorn like tail, in my design, Unicorns don’t have Equine tails. Pound Cake has larger wings and since ponies can fly very early, he has fully developed flight feathers. Other wise their designs are the same except for their manes, they don’t have any hair on their head, instead, their mane is on the back of the neck. Real life foals’ manes are very short and on the back of the neck only. Here you guys have it, I’m happy with the foals’ slight design change.
