The Attack episode 21 aired on April 13, 2015. It was hosted by Kevin Pereira, Alex Corea, and Alison Haislip.

For a donation goal, Alex and Yaniv slid down a makeshift Slip n Slide filled with nasty stuff.

Liz Forkin Kunert appeared on camera very briefly at the end of the episode. This was Liz's first appearance on the show.
