Fuzzy green aliens? Not quite, but that doesn't make the colony of living balls that took up residence on an Australian beach last weekend any less peculiar.
"They're actually a really unusual growth form of seaweed, because seaweeds mostly grow on the rocks but occasionally they get knocked off and rolled around in the ocean forming these beautiful little balls. It's quite an unusual phenomenon, it's only been seen a handful of times around the world."
