Pandora Bladder Polyp
Blue Bladder Polyp in the Valley of Mo'ara at Pandora - World of Avatar in Disney's Animal Kingdom at Walt Disney World, Orlando, Florida.
I do not know if this is an alien fungus or not. Hoping someone might now the exact Pandora name. The green plant behind it is terrestrial and called Arrow Head.
I share other colorful photos from the Beauty of Pandora on my All Ears blog.
