At 6:34, Mahomes describes the Allegretti-in-the-snowglobe play.
As you can see from the play, Allegretti then runs to Orlando Brown's shoulder, Wylie is eligible and runs a route, and the entire line is supposed to shift over, so it's Smith (RT), Humphrey (RG), Thuney (C), Brown (LG), and Allegretti (LT). Wylie splinters off, and the defense is supposed to be so confused Mahomes hits Wylie for a pass.
Since Wylie is an avid Pokemon collector, they called the play "Pikachu Gotta Catch 'Em All."
The Eagles not only diagnosed the play properly (Mahomes calls out S Marcus Epps), they also rushed five, making it hard for the entire OL to shift over. You see Humphrey in the play try to overtake Smith's guy, but Smith can't get off him and get to the rusher on the right edge in time.
Wylie is actually covered, Mahomes throws it away.
Incredible work by Epps in diagnosing a goofball play he's probably never seen before.
