Ninja Balls are the inhalable food invented by Ryan J. Reynolds in Episode 28 of WillyousignmyCast that you throw down onto the ground like an actual ninja ball, let the smoke/mist fill the room, and ingest the flavor of your favorite foods as opposed to actually spending large amounts of money on the foods themselves. For example: Hot dog, pizza, salad, pork bacon, shark and sharktopus.

WARNING: 40% alcohol content...
Ryan: Ninja Balls are the way of the future.
Brian: Ninja Balls are the way of the STUPID.
Ryan: That's like saying you can't do the printing press or the telegram because it's impossible. Ninja Ballin' like a mothaf*cka!
