Scientists gave octopuses MDMA... and they started dancing and touching others.

After hanging out in a bath containing ecstasy, the animals moved to a chamber with three rooms to pick from: a central room, one containing a male octopus and another containing a toy. This is a setup frequently used in mice studies. Before MDMA, the octopuses avoided the male octopus. But after the MDMA bath, they spent more time with the other octopus, according to the study published in Current Biology. They also touched the other octopus in what seemed to be an exploratory, rather than aggressive, manner.

"Whoa, dude! Can I touch your face? I'm gonna touch your face."

But yes, the octopuses acted like they took ecstasy. At first, when they received a little too much MDMA, they breathed erratically and turned white. But on lower doses, one animal “looked like it was doing water ballet,” swimming around with outstretched arms. Another spent part of the time doing flips, and another seemed especially interested in minor sounds and smells.

"Have you guys ever tasted the water? I mean, REALLY tasted the water?"
