How to Summon All 3 Mechanical Bosses in Terraria | Terraria 1.4.4.9

I'll show you how to spawn all 3 mechanical bosses, so you're probably already in hard mode.
But if not, then in order for the game to go into hard mode, you need to get a voodoo doll from killing Demons in Hell.
Then throw it into the lava and kill the wall of flesh that appears.
Now we are in the hard mode.
Next, we need to get some resources.
This is Soul of Light, which is obtained from all mobs in Underground Hallow. And Soul of Night, which can be obtained in Underground Corruption or Underground Crimson, depending on the type of evil in your world.
We need these two items in the amount of 9 pieces, both of them to summon all the bosses atlest once.
You should already have all the other resources because they are obtained during the progression to the hardmode game.
So let's get started.
To craft a Mechanical Eye, we need
3 lens
5 any iron bars and
6 Souls of light
And we combine all this with the help of a Mythril or Orichalcum anvil.
And now we have a item for summoning the Twins.
Next up will be the Mechanical Skull
To create this summoning item, we need the following items.
30 bones
5 any iron bars
3 souls of light and
3 souls of night
And you need to combine all of this on a Mythril or Orichalcum anvil.
Now we have the Skeletron Prime summoning item.
And the last boss is The Destroyer.
To summon him, we need to craft a Mechanical Worm.
And Mechanical Worm is crafted from the following resources.
6 Rotten Chunks of Vertebra
5 any iron bars and
6 souls of night
And of course, all these items are combined on the Mythril or Orichalcum anvil.
So we got the item to summon the last boss.
This is how all these items look like.
Bosses can only be summoned at night.
And this is what the bosses look like
Thank you for your watching, goodbye.

On a GFB world, you could also spawn in Mechdusa which, quite literally, spawns all 3 mech bosses at once

One important question can you still get the chat "the jungle grows restlessly" even with player spawned mechanical bosses?
