Froopyland

Froopyland is an artificially crafted alternate dimension, created by Rick Sanchez some time in the 1980s. Rick modeled it to look like a happy, imaginary world, for his daughter, Beth Smith, when she was a child. It appeared in "The ABC's of Beth".

Froopyland is accessible through a collapsed tesseract that activates by simply drawing an entranceway with an advanced piece of chalk. Froopyland consists of a massive area that includes mountains, forests, swamps, and likely other biomes. The weather is always perfectly sunny and warm with procedurally generated clouds rolling across the sky. A river of a literal rainbow cuts through the land with a stunning waterfall. The ecosystems are largely fantasy inspired as there are literal swamps of honey. Froopyland was designed by Rick to be an incredibly safe place for Beth to play in. All ground surfaces are bouncy to prevent fall injuries and the rainbow river's water is breathable to prevent drowning.

Rick also included a fairy-tail esque castle within Froopyland for Beth.
