Surface GUI Behind Another Surface GUI Not Showing – How to Fix?

Hey, im new to developing games and I want to have a little easter egg in my game. The only issue is im using a surface GUI to hide it so the part can be transparent, however it seems that when I place it behind another part with a surface GUI it turns invisible unless I have “AlwaysOnTop” as true, but then its visible through parts. Is there a solution to this or am I going to have to deal with it?


The blue guy there is a Billie Eilish reference, heres a second image to see what its placed on.

(Theres a transparent part there)

from the first image you can see it through a part since I have AlwaysOnTop enabled, but my issue is I can see it here aswell:

Does anyone have a solution to this problem?

I want it to show behind the surface gui, but im not sure if surface guis can be placed behind one another.
