Playing with Taterzens
What is a Taterzen?
It's a rather silly nickname for NPC, which stands for Non-Player-Character.
It can be summoned with /npc create <name of the taterzen>.
If you prefer using a GUI, just run /npc and navigate to create node.

GUI navigation
To use GUI, enter /npc command.
Gui is created from command itself, therefore it has same child GUIs as commands.
Inputs to GUI are handled via anvil GUI.
- to execute a node, right click the item in menu
 - to go to child GUI, left click the item in menu (if there's no more child GUIs, left clicking will execute it as well.)
