What are the cans of "Fizz" drink for?

Collect the cans of "Fizz" drinks - their power can help you do the "Super Burp"

and thus knock out any Security Guards in site!

Use the SpaceBar to perform a "Super Burp"

Just one burp will clear the screen of Security Guards!

But, be careful - the "Super Burps" only work on Security Guards!
