Wave
A new mob type, referred to as the Wave, will be introduced in the world of Minecraft Pocket Edition following the installation of the mod “Wave“. You can summon it using a few redstone blocks, and it will then fly around, creating various patterns in the sky. It will actually attack you if you’re in survival mode in MCPE, so you need to be cautious. It’s certainly unusual, but in a good way.
The leash knot is now replaced by the Wave in Minecraft PE (the leash knot is what you use to tie something to something else, like an animal to a fence or similar).
Place several Wave items in a dispenser. Then, set up a button on the dispenser or connect a button to redstone.
All that’s left is to press the button to summon the Wave in MCPE. You can create as many as you like, but be aware that if you spawn too many, you might experience lag and delays in the game.
