In @joecooldoo's "Baldis Basics and Education and Learning" game, removing the map background will make the 3d map the shape of the turtle, because it defaults it to the turtle when there is no costume. But, there are 2 pixels behind it, and the render block only makes what the is on the current costume.

So this begs the question, is the turtle hiding something?
If you ask a sprite to switch to a costume that doesn't exist, it will default to the turtle costume.
The turtle's not "hiding something", but it does have some strange properties.
Oh, I just realized what you mean.
The turtle costume doesn't have any content, and using "pixels of" on it will return blank. This map shouldn't even be rendering correctly in the first place.
Also, could you please link the project?
The turtle's costume includes a black border and a white border so that any pen color will be visible against any background color:
One of the ongoing fights between Jens and me is about whether the turtle shape is a costume. Jens views it as the sprite's naked body, whereas I think it should be considered a costume like any other. In particular I think NEXT COSTUME should switch from costume 0 to costume 1 instead of just silently not doing anything. But also this is why PIXELS OF COSTUME TURTLE doesn't work.
