Convivialious uses the Pet Code Scam, advertising a Rare Pet Mouse code.Several times, they have met up on Google Hangouts to discuss trading the custom mouse. They refuse to go first, even though they could easily make the mouse and trade it for another person's items. They require the person they're trading to risk their rares in order to receive the mouse made after.
They most likely don't own a mouse code, as it was proven that the images they showed were found online. They also contradicted themselves, showing a screenshot of "their" mouse code (found online) and then saying that they weren't able to take pictures.
