Before 3x11, Zelena was probably looking for a way to travel to Storybrooke since all what she needed to cast the time travel spell was there: Regina's heart, Charming's courage, Rumple's brain and the baby.

Conveniently to Zelena, Regina reverted the Dark Curse in 3x11 and took them back to the Enchanted Forest.

We already know that Cruella and Ursula were in this world, but we don't know they came here from the enchanted forest. Maybe Zelena was involved somehow.
