It’s a triple multivortex with 2 orbiting subvorticies around a central main vortex. in real life, tornadoes such as this will often wedge out after 3-4 mins and make a monster wedge. this is an EF5 tornado.
if you were that close to the deadman, multiple grass blades would be lodged deep into your bone, thankfully roblox lets us have the experience of witnessing one at close-range. not the best in quality, or budget, but it was the best thing roblox could offer for tornado-sighting experiences like this, in it's time period. truly, the deadman walking
For those who are wondering if it has another name, these are called sub vortices. If you see these kind of tornadoes, get out of there immediately, the tornado can be bigger and can suck you in at any moment. Or idk their maybe called multi vortex
