My son who is on the autism spectrum has recently been obsessed with these and I’m really trying to learn and understand so I can relate to him and possibly be able to surprise him. So I need to know everything there is to know is this a tv show or a video game? What is it about? How does one play it?
Today I seen him playing a game with a keyboard and I guess you spell the characters on the keyboard and if you get it right the character shows up. I guess there’s also a specific order of the characters (I’d like some confirmation about that and a list of there is one). His speech is limited that’s why I can’t ask him I tried playing said game with him today but I couldn’t make out most of what he was saying the only characters I got were NICKEL and ROBOTY. Anyways I hope you guys can spare a minute to help me understand. Also does this have any relation to SPRUNKIS? He was obsessed with those as well. Thank you
