PLEASE HELP! how would I make 3d trails like in a sonic game

[FinallChase]

How do I make the type of trail a sonic game would have with an airdash? Already explained in my other topic, along with the video:

3d trails, like in a Sonic game?

How would one make 3d trails like in this video, at 0:48? If you look closely, you can see that the trail is a 3D cylinder, but that makes no sense because trails can only have one attachment. Help please? [Amazing Sonic Heroes Inspired ROBLOX fan game: Sonic Totems]

If anyone knows how to do this it would be greatly appreciated
