Okay, so we have to admit something to you: This isn't actually an origami craft in the strictest sense of the term. Origami dictates that an object be folded into being from a single sheet of paper, but for this goldfish we take a bit of a shortcut, literally. Instead of folding to get all the pieces in place, we make a few cuts to facilitate the fish-forming process.
This is called kirigami, where you use scissors, but only a little bit. After you're done, draw an eye on it and make it even more realistic. Hope you enjoy!
