Birthday Cake Sticker for Streamers Birthday!
It just crossed my mind that it would be really cool if there was a sticker that streamers could activate on their birthday. The viewers would be able to use the sticker for free like once per- hour, and the streamer would get x sparks. It could be just a sticker or one of the cool animated ones that puts an overlay on the chat.
Just a little extra shiny, even if it wasn't free to the viewer just another sticker that was like the Mixer cake or something would be pretty spiffy
