1/ In the doorway of an ancient tomb, Gizmoduck holds open a heavy stone door threatening to slam down and trap our intrepid adventurers. Scrooge and his nephews are barreling under to avoid being crushed, trying to get back out into the desert sun and away from the crocodiles that are chasing them.
Gizmoduck: Not to worry, Mr. McDuck! I have everything under control!
2/ Scrooge points with his cane out to the helicopter kicking up dust and sand several hundred feet away.
Scrooge: Hurry, lads! This is no place for ducks!
3/ As they pile into the copter, Launchpad is sitting at the controls.
Launchpad: Hey, Mr. McD, uh... Weren't you supposed to have some big egg?
Scrooge: Aye! But it's better left--
4/ Huey, Dewey, and Louie all press themselves up against the window.
Huey, Dewey, and Louie: Gizmoduck!
5/ They slump down in their seats. Scrooge and Launchpad exchange a nervous glance.
Huey: He's-- He's gone...
Gizmoduck (OP): Not to worry, Gizmo-Buddy!
6/ Clinging to the bottom of the copter with one hand and batting at the crocodile still attached to his wheel with the other, is Gizmoduck. The tomb they're flying away from, revealed at last, is actually an enormous nest.
Gizmoduck: We'll just have to make due with regular-sized omelettes...
