Then she goes to the Canterlot library and finds a book titled Cipher which has a yellow triangle with a eye and hands with a tie on his middle. Curious, she picks it out and teleports back to her tree house. When she picks a page she sees the words to summon Bill Cipher, she reads the words, summoning Bill Cipher.
