Laser guns replace guardians and the easiest way to get them – from inventory in creative mode.
After you place them, you will notice that they are bouncing. Just stand next to them, and they can choose you as their owner, on whose shoulders they will settle. There is also a steampunk robot suit (replaces a creeper), and it can be used as a riding horse. It can run very fast and jump high enough, never getting hurt from falling in the ICEP.
