Meet Spring-Step :3 (Spring on the left, Step on the right)

A pair of twin ponies that are joined together like a slinky :3
they are able to move around like a slinky too, with one jumping over the other and doing it on repeat.

Spring is the more shy and reserved one of the two, as she likes to keep to herself most of the times and doesn't do a lot of talking in public, only for close friends and her sister. She is also self-conscious about her body and feels like she belongs in a normal ponies body.

Step is the more cheerful and outgoing and cheerful of the two, as she can be very hyperactive and carefree, and has a lot more friends compared t her sister. She also takes joy in her body, feeling that it makes her and Spring unique compared to everyone else.
