The Nintendo Labo Toy-Cons just never fail to surprise. Remember the fishing game? While it is confirmed you can create your own fishes, they never told you that you can do it with the help of the Toy-Con Piano.
Things could not be simpler, all you had to do is to insert a paper cut out of any shape and fit it into the top slot of the Toy-Con Piano for the IR camera to scan. Your unique fish will take the shape of your cutout. You can then use the piano keys to change the colour of the fish.
This goes to show Nintendo has thought out of all the ways to utilise the $70 cardboard that you’re going to purchase.
