I'm tempted to translate this for folks - the currently up Google Doodle - as these symbolism codes are oft the most telling way (outside of comms from Q) of knowing wtf is going on in the world.
the easiest one to translate is the shovel - tho they all have meaning. Basically saying anyone who digs will only find planted cultists screaming at them.
it gets a three scoop ice cream - the colors and the red cherry on top all have meaning. As for what it is? To be honest I have a theory but I'm not 100% sure and I'm only half fluent in cult so I don't want to give the wrong guess.
