Feature: Prevent Duplicate Creature Generation

[itmilos]

As a creature generation system
I want to prevent the creation of a new creature
If a creature with the same name and wallet already exists

Scenario: Attempt to create a creature with a duplicate name and wallet
Given a creature with the name "Dragon" and the wallet "Wallet123" already exists
When I attempt to create a new creature with the name "Dragon" and the wallet "Wallet123"
Then the system should prevent the creation of the new creature
And display an error message "Creature with the same name and wallet already exists"
