FISH (cipher)

Okay kiddo, let's talk about something called the fish cipher. A cipher is a secret code that people use to hide messages from others who they don't want to read them. And fish is a type of cipher that is really complicated to break!

You see, fish works by taking the letters of the message that you want to hide and mixing them up in a very specific way. It's kind of like playing a game of catch with your friends but instead of tossing a ball back and forth, you're shuffling letters around.

To do this, you start by writing your message out in rows of letters. Then, you go through each row and swap the letters around in a certain pattern. It's kind of like dancing - you have to follow the steps in order to do it right!

Once you've shuffled all the letters around, you end up with a jumbled-up message that is almost impossible to read if you don't know the trick to unscrambling it.

This might sound like a lot of work, but it's actually a really important thing to know how to do when you want to send secret messages to your friends or family. Just remember, though, that you always want to make sure that you're using cipher to protect something important - like a special surprise or a secret message - and not to do anything bad or hurtful.

But don't worry about that right now, just have fun playing with your friends and your secret messages!
