The object's physical appearance is unknown. It was only briefly mentioned in The Pranking Quarterly Magazine where it said:
- "...then he [Danny] belched in our faces, and it smelled like he used The Burpinator, his previous creation."
- ―The Pranking Quarterly Magazine.
The Burpinator's function is technically unknown, as the only time it ever appeared in the series was in the quote above. However, it is assumed that it makes the user belch loudly. This, although very unlikely, could have been used by Danny to win the Slurp & Burp Convention in Season 2. But no use of an invention was ever recorded in that episode, so again, this is extremely unlikely.
