B3313 | Collecting the 5 fake stars

In B3313 there are 5 fake stars that are possible to collect without using cheats.
A fake star is a star that won't be added to the total if you collect it and the game won't remember that you collected it. This means that after you collect them, they will still look as if you haven't collected them yet.
Obviously these stars weren't meant to be collected in the first place, but it's still fun to do so :)
This is a video guide on how to collect these 5 fake stars.
DISCLAIMER: These fake stars have certain requirements that have to be met and they can be missed if you don't collect them soon enough, so make sure you meet their conditions if you want to collect them.
For example, one such requirement is the player having 0 red stars. This is due to the fact that 4 of these 5 fake stars are only possible to collect due to instant warps being disabled before you collect your first red star, and 4 of these fake stars will warp you away before you can collect them.
The order in which to collect them is arbitrary, so they can be collected in any order you want, but personally I recommend doing it in the order shown in the video.
UPDATE: B3313 v1.0.1 fixed many of the game's warps taking you to either Plexal Lobby or Plexal Upstairs. What it means for this video is that dying in Bowser in the Dark World (Shoshinkai) doesn't take you to Plexal Lobby anymore, but instead to Beta Lobby A. You will have to get to Plexal Lobby in a different way.
