Hi!

I said I was working on a BIG thing, but that was because I needed to figure it out.

If you want to build it step-by-step:
1.Copy the contraption on the 2nd picture in a square pattern or a line (There's water behind each sugarcane. Keep in mind that you can only place sugarcanes on sand on dirt, so use the one that is available to you.)
2. Put a piece of redstone behind each Observer (for those who don't know it's the thing with a bored looking face)

Hope you enjoy it!

Also, in this world I set the randomTickSpeed to 400. Just so you know :)

Bye~!
