okay so this has kind of been a thing for a while in my head, but splash is non verbal. This stressed his moms out a lot, Alphys especially because now she severely doubts her parenting abilities. Splash really didn’t like seeing them so upset so, basically in a night, in the garage lab with no supervision (don’t try it at home kids), he crafted a sort of AAC device out of a robotic fish toy.
Undyne is like “WOW my kid’s so good damn smart!!!!!! >:)” and alphys is moreover “how in the world did she make that in a night”
The one in the comic i imagine, is just a prototype, so he probably makes a more robust one in the future.
also very huggable in case of emergency
