What is the name of the short film featuring Jack-Jack's powers?

The short film featuring Jack-Jack's powers is Jack-Jack Attack. This 2005 Pixar animated short follows the Parr family's baby while he is being babysat by Kari McKeen during the events of The Incredibles.

The short grew from a scene considered for the feature film but ultimately cut and expanded into its own story. Kari discovers that Jack-Jack is not powerless, as the family initially assumes: he can teleport, float, pass through solid surfaces, burst into flames, and display several other abilities. His unpredictable powers turn an ordinary babysitting job into comic chaos.

Jack-Jack Attack was written and directed by Brad Bird and included with the home-video release of The Incredibles. It also features Rick Dicker interviewing Kari afterward and using a memory-erasing device, tying the short directly to the film's superhero-cover-up world. It is not the same as One Man Band, Lifted, or Boundin', which are separate Pixar shorts.
