Party on, Thor! These are the good-timeMCU and Marvel Easter eggs in the latest installment of What If...? As proven by Loki, Odin's decision to adopt a little bundle of Frost Giant joy was a pivotal moment in MCU history, but What If...? episode 7 asks how the timeline might've changed if Asgard's ruler handed Loki back. Thor grows up an only child, and without Loki to bring the games and mischief, turns into something of a party animal. More vain and spoiled than Chris Hemsworth's live-action character, the God of Parties arrives on Earth for some Norse-flavored shenanigans.

What If...?'s Thor episode is a more upbeat adventure (nearly...) after weeks of pain and misery thanks to zombies, Killmonger and Strange Supreme. Thor's love of drinking and planet-sized phone book invites plenty of MCU Easter eggs from across the Marvel galaxy, and the cast this week includes Chris Hemsworth, Natalie Portman, Kat Dennings, Tom Hiddleston, Clark Gregg, Cobie Smulders, Frank Grillo, and Samuel L. Jackson.

A very different, Easter egg-heavy affair, here are all of the MCU references, guest cameos, writing nods, and clever in-jokes that accompany Thor Odinson as What If...? asks... what if The Hangover was a superhero movie?

Jane Foster's Van From Thor

What If...? episode 7 opens on a shot of Jane Foster and Darcy Lewis' van. Designed especially for staking out gods with flowing blond hair in the middle of the night, the same vehicle was seen in 2011's Thor movie, used by Jane, Darcy and Erik Selvig. They even ran Thor over with it (by accident, of course).

Taika Waititi's Pineapple Shirt

One ofWhat If...?'s more prominent Las Vegas tourists is wearing a pineapple t-shirt, which feels like a nod toward Thor: Ragnarok and Thor: Love & Thunder director, Taika Waititi, who famously wore a similar garment before giving it to his Korg character in Avengers: Endgame. Pineapple Shirt Guy is later spotted drinking with Lady Sif and avoiding Korg's cannonball, suggesting the Waititi reference is probably intentional.

Lady Sif & The Warriors Three

Instead of landing in the New Mexico desert as the fallen prince of Asgard, Thor arrives in Las Vegas, proclaiming himself the party savior of Midgard. Arriving via the Bifrost bridge, Hemsworth's character is accompanied by (from left to right) Fandral, Lady Sif, Volstagg, and Hogun. Mjolnir isn't missing the fun either.

Thor & Loki Changing The "Fate Of A Universe"

Introducing this week's episode, The Watcher describes howThor and Loki's sibling relationship "changed the fate of a universe." Obviously referring to the primary MCU timeline, it's interesting how cosmic beings view the brothers' importance to history. It was Thor and Loki's feud that resulted in the Battle of New York, the formation of the Avengers and, ultimately, saving the entire universe from Thanos. Last week's What If...? scenario suggested Ho Yinsen started the MCU by helping turn Tony Stark into Iron Man. This week's offering proves Thor and Loki played an equally vital role.

Casket Of Ancient Winters

Past What If...? episodes began by animating key moments from MCU canon, such as Tony Stark forging his first Iron Man armor, and the Avengers assembling in New York. This week's Party Thor montage instead depicts unseen moments from Thor and Loki's younger years, and here we see the God of Mischief playfully freezing his brother using the Casket of Ancient Winters. Stolen from Jotunheim by Odin, Loki would use the weapon in 2011's Thor. Interestingly, it was the casket's magic that revealedLoki's true, blue Frost Giant appearance as an adult, though Loki's form in this image is unchanged.

The Odinsleep

Explaining how Thor came to be reveling on Earth, What If...? episode 7 shows Odin enter the "Odinsleep." This plot point hails directly from 2011's Thor, where the Asgardian ruler began a long, magical slumber, allowing Loki to seize control in his absence. Obviously, Frigga didn't see the Odinsleep as a vacation opportunity in the main MCU. Perhaps the different attitude can be attributed to Frigga not having that close parental bond with Loki in What If...? The animated Odinsleep scene is framed remarkably close to the live-action version, but with Thor taking Loki's place at his father's bedside.

Odin's Fake Infinity Gauntlet

As Thor and his pals sneak off to show Earth a good time, the quintet pass Odin's Infinity Gauntlet. The golden glove was included as a vault Easter egg in 2011's Thor movie before the franchise had properly decided its long-term direction, leavingCate Blanchett's Hela to reveal the trinket was just a fake.

Guardians of the Galaxy's Kraglin

And so begins a rapid-fire guest list of party attendees from across the MCU. Here, Lady Sif is spotted drinking with Pineapple Shirt Guy and a Ravager who looks very much like Kraglin, who would've been working under Yondu at this point in the timeline. Though the character doesn't look exactly like Sean Gunn, Kraglin's mohawk makes him stand out among the other background Ravagers.

Party Skrulls & Yondu

The camera pans around to reveal more familiar MCU faces answering Thor's call for Midgard mayhem. To the left, a group of Skrulls can be spotted cheering for the God of Thunder, while the blue figure on the right appears to be Yondu - Michael Rooker's Guardians of the Galaxy character, identified by his purple headgear. The Skrulls are later witnessed showing off their shape-shifting abilities to a deeply impressed Thor.

Karl Urban's Skurge

As more and more party-goers arrive in Vegas, What If...? reintroduces Skurge, memorably played by Karl Urban in Thor: Ragnarok. Though he doesn't get chance to speak and isn't acknowledge by name, the facial hair and armor give him away. No doubt Skurge enjoyed getting a "thunder hug" along with his tankard of ale.
