Gru has what looks like a pin-up of sorts of Belle above his door. She's holding her ball and chain.

There's a diagram of Jean-Clawed by his bed and a smaller poster of Wild Knuckles below that.

He has figurines of Belle and Jean on the floor.

He has a sizeable boomerang/slingshot/saw collection. Also spaceships. Some of them are even labeled.

+ spider wallpaper.

A picture of Nun-Chuck on his wardrobe, as well as a newspaper clipping with the headline 'Nun-Chuck Tells It All'. A stylised V6 poster above that, and an article on Stronghold to the side.

The queen's crown he stole in Minions. I've done the maths, and it would seem he stole it when he was 4 years old. The timeline is a bit of a mess, but personally I see the present Despicable Me movies (1-4) taking place from 2009-2014. Maybe that's a bit generous.

They also 'sing' a version of Cecilia by Simon & Garfunkel (released in 1970) during this scene. Available on the soundtrack.

This minion singing into a wrench.

Bob's pet rat from Minions is still alive, somehow. Wild rats typically live to be 1, sometimes 2 years old. The oldest rat ever lived to be 7 years old. It's been 8 years since the first Minions movie. Go figure. Or, we could just say this is a different rat.

This minion casually on fire. These guys are literally indestructible.

Otto passes out. So these guys do need to breathe. And have blood.

A few things:

Gru's clock is a bomb. There is also a stylised print of Jean-Clawed above it.

More giant V6 posters + a giant poster of Wild Knuckles.

A small poster of Stronghold on the right.

A drawing of Belle Bottom beating up some police officers + a drawing of Nun-Chuck + drawing of Svengeance.

Newspaper clipping that reads 'Jean Clawed Snaps Again'.

There are more but they appear again in a bit.

Other than the giant V6 banner, there is a news clipping from 'Despicable News' I deciphered as saying 'Veni Vedi Vicious 6', a play on 'Veni Vedi Vici': I came, I saw, I conquered. Not sure what WK is doing but he's on the cover.

This is just here for the sake of it. Stronghold has the disappointed-dad look going on. Svengeance looks like someone told him to show his mean face.

Bob and Tim from Minions. Reminder these guys are millions of years old.

The VNC guy from Minions is back with a new 70s style.

Sucky 70s graphics, I love it.

Wild Knuckles has a black eye and a bandage where his bandana used to be. Let's not question how he survived or made it back in one piece. Humans seem to be nigh-indestructible in this universe.

Skinny henchman nudges bigger guy to ask about payment while WK makes some questionable hand gestures (pulling limbs? breaking bones? who knows.)

WK suddenly grows 3 extra arms. He actually has a few blemishes and freckles on his arms which is just cool attention to detail.

Gru's future crocodile couches; he clearly inherited them.

Gru sings to the tune of 'Bad Moon Rising' by John Fogerty and CCR (released in 1969) throughout the 'getting ready' scene.

These guys really merched up. Wild Knuckles comes with glasses. Just look at those posable joints.

There's also a drawing of Nun-Chuck holding something (probably stolen)

Drawing of Jean-Clawed beating up an old lady with an umbrella.

Gru's self-ship of himself with Belle.

TBC. Wow, 2 posts in 1 day? Amazing. I'm totally not procrastinating on something.
