Why does Sci-Twi’s pony up from have wings even though she’s not an alicorn?

[Snoopy Fan 8,119]

In Spring Breakdown, we saw that as a pony, Sci-Twi is just a unicorn so why does she have wings while in her pony up from?

From my understanding, it seems that Twilight's wings are just Midnight's, but since she overcame her fears, Midnight's wings changed in appearance to that of Pegasus. Hope this helps in answering your question
