If the dad is anything like my mom (the good parent), Pikachu will just get grounded or in more trouble. Honeslty, its dishes, who cares about a cup? And everything you just said will get them in trouble, such as talking back and disobeying by watching it even when Pika was told not to. Pika's parents are smart, if Pika wont do the dishes, there will be consequences, thats how to teach a kid to do the dishes. Tbh, it just sounds like a temper tantrum that will diffuse a few hours after the situation. I know because i have had them. Honestly, it would just benefit Pika to do the dishes like they were told to, it will avoid more punishment and depending on what their parents are like, their parents may allow them to watch the superbowl if they get the dishes done. It isnt unfair, its actually good parenting.
