A BRIGHT green, alien-like slime has taken over the Mooloolaba Wharf Marina.
Local Bo Hanson saw the substance oozing out of a pipe in the waterways and posted the pictures on social media.
"This is coming out of the storm water drain at Mooloolaba Wharf Marina," he posted.
"Bright green. Not mixing with water...any ideas. Council did work on this drain a few weeks back."
What do you think the green slime could be?

This is not a scientific poll. The results reflect only the opinions of those who chose to participate.
In December the Maroochy River turned a lurid shade of neon green, in a stunning visual display of nature.
The green slime was "stinky" and clung to the rocks and in the shallows along the river for more than a few hundred metres, from Chambers Island up past the Cod Hole.
On that occasion, Maroochy Waterwatch and ECOllaboration CEO Cerran Fawns said the slime was most likely an algae called trichodesmium, that blooms when conditions are just right.
With so many nutrients being flushed out of the rivers, combined with the heat and sun light, the algae would bloom.
She said it would've washed up river when the tides, currents and winds aligned to push it inland from the open ocean.
She said it can go from bright green to blue then a red-brown, and three years ago had turned Cornmeal Creek a vivid blue.
Ms Fawns advised people to "always stay out of it".
