Quackos (The Elder One) is a giant duck that is added to the popular video game Minecraft
using Hbm's Nuclear Tech Mod which is a mod that adds advanced energy, machines, reactors and technology. Quackos is absolutely huge and is unkillable, the only way to remove the elder one is to feed it peas, which is another item added by the Nuclear Tech Mod. Quackos behaves like a vanilla
minecraft chicken, but it makes quacking sounds, similar to the duck mob, that is also added to the game using Hbm's Nuclear Tech Mod, but quackos makes deeper sounds with echo.
The way to summon it in Survival mode is weird. You have to first summon a duck by pressing O at the beginning of the game. You can summon only one duck so take care of it. Next, the duck has to receive radiation. The easy way to do this is by running an uncoated
nuclear reactor next to the duck. Enough radiation will turn the duck to quackos.
Quackos acts like a normal chicken and does not attack, but they multiply, so you might want to keep them under control if you have a potato pc. Removing them after there are many is painful (
i know this by experience).
