i looked into the code for chapter 5, and the special "your" speaker it used briefly in c4 is gone, sadly. it doesn't show up anywhere else, either. if anyone was curious, the sprite is called spr_npc_diamond_sleepy. it's a derivative of the unused sleeping rudinn sprites, so that makes sense. all the rudinn sprites are just called some variant of diamond.
bluedinn for your viewing pleasure, although i just bullshitted the frame rate because i don't know how to find image_speed in this program. fresh from the [UndertaleModTool]. maybe i will post about it on my ut blog later. i like bluedinn. it's blue after all.
