The episode title (and the villain's name) is this combined with Genius Bonus: Toth and Ra are Egyptian gods that are portrayed with the head of an ibis and a falcon, respectively, which are quite fitting for a show that stars anthropomorphic birds.
Toth-Ra and his followers are all designed after Egyptian gods: either falcons (based on Ra or Horus) or jackals (based on Anubis).
The way Scrooge and Launchpad convince the Living Mummies to revolt against Toth-Ra is actually a nice allegory for American foreign policy.
Toth-Ra, as a Puppet King, gives the denizens of the pyamid basic necessities and regulates and controls their life, giving them no direct reason to revolt. So Scrooge's usual arguments to get them to revolt doesn't work but Launchpad chugging his burrito gives them a sense of the outside world and what they are really missing (literally, since the contents of the burrito wrap, and the burrito itself, are all New World crops outside the ken of the Mediterranean and the Nile Delta).
Launchpad's big rebellious speech about the burrito, and the multiple various kinds available outside, demonstrates how consumerism is associated with freedom in America, which we see when the rebels initially fight for the burrito but then decide that it's really about freedom. But at the end, once they're outside, they line up near a taco-stand, which might be an American chain restaurant.
Scrooge himself ironically is ambivalent about this. Despite being an adventure capitalist himself, he's personally quite anti-consumerist and as an Adventure Archaeologist, consumerism and its spread, takes away the joys of adventuring, gentrifying every Hidden Elf Village, ruining the glamour of "the greatest archeological find of our time" (as he points out), and he's dismayed that the Living Mummies give Launchpad a priceless artifact (which Scrooge values) while they give Scrooge a burrito they made by themselves (which they value but Scrooge doesn't).
While it seems strange that the Living Mummies would be willing to fight for burritos but not for, say, more sunlight or smaller sacrifices, it actually demonstrates relative deprivation theory. The Living Mummies perceive their meager crops and tiny living space as the status quo, so they don't seek to change that — but introducing a new commodity to their society that is apparently commonplace on the outside induces them to rebel to obtain it.
Toth-Ra is a lot taller than his subjects. In ancient Egyptian art, kings and rulers were always depicted as much larger than commoners.
Toth-Ra is Weakened by the Light. So, the door at the top of the pyramid that allows sunlight in was most surely built in to have a way to stop him in case he got back to life, as it eventually happened.
When spotting Louie behind his throne, Toth-Ra, instead of charging towards him, grabs a casket and tosses it at him. Since the throne is beyond the sigil, directly going for Louie would make the mummy inanimate, so he resorts to throwing things at Louie instead.
If we assume $4 for the quesadillas, $5 for the tostadas, and $8 for the burrito especiales, the total for Launchpad's order at the taco truck comes to $2275. This is why Scrooge balked at covering the meal upon hearing the cook charge $9000; part of being The Scrooge is knowing when you're being gouged for extra.
Fridge Horror:
The guard comes very close to killing Louie and Webby for being where they shouldn't. At the time, Scrooge had no idea where they were and was worrying for their safety. How would he have reacted if he'd found out two of his charges had died?
Sure, the heroes push back Toth-Ra's body behind the sigil where his corpse becomes inanimate again. But imagine what happens if another Adventurer Archaeologist comes back to the tomb and makes the mummy cross the sigil again...
The pyramid's community has lived sealed off from the world for thousands of years, but only seems to have about a hundred people. In real life, a self-contained population can only remain genetically healthy with a much larger population… or ruthless culling of genetic defectives.
