Perfect Rhymes (but not great for the meaning):
* Unfurled (doesn't fit the theme)
* World (too basic and obvious)
Near Rhymes (more fitting):
* Unfurl (suggests a magical unfolding)
* Twirl (can evoke movement and fun)
* Swirled (similar to "twirl" but more visual)
* Hurled (a playful contrast to the happy place)
* Curled (might suggest cozying up)
Other options:
* Disneyland (a bit obvious but definitely relevant)
* Adventureland (a specific area of the park)
* Fantasyland (another park area)
* Tomorrowland (yet another park area)
Ultimately, the best rhyme depends on the context of your poem or song. Good luck!
