NHL's Golden Knights Unveil Insane On-Ice Show Before Kraken Game

What happens in Vegas certainly shouldn't stay in Vegas -- at least when it comes to pregame hockey shows -- 'cause the Golden Knights unveiled a wild one on Tuesday, and it was INSANE!

Just minutes before the Knights opened their season against the Seattle Kraken ... the team showed off a virtual masterpiece on their ice to hype up the home crowd.

The show started with a giant octopus circling underneath the rink, while a knight mascot skated above it.

Eventually, the squid busted through and put the knight in danger ... and the optics of it all looked like a scene straight out of a Hollywood movie.

The knight, of course, ultimately came out on top of the giant creature ... which sent the crowd into a frenzy and absolutely lit up social media.

The pregame juice seemed to help the Knights too ... 'cause Vegas ended up winning the season-opener against the Kraken, 4-3.
