Nice video. I found The topic of Robotnik surname and it's connection to Polish word "Robotnik" (meaning "Worker") most interesting, but I am a bit sceptical. I've checked, and although the name Ivo exist in Poland, it's really rare (around two hundred kids were named "Iwo" in 2017). I'll elaborate on it a bit more in the coming days, as I have to do a bit of linguistics research. Edit: edited for clarity.
