Vanillaware's latest title, 13 Sentinels: Aegis Rim, finally landed on Switch yesterday, letting you bring the mystery-laden, mecha-battling, mind-bending story on the go with you. But if you have a physical release of the game, it seems like the surprises start even before you get a chance to boot up the game.

A few days ago, Twitter user @5wayshot got a boxed version of the game ahead of time. When they open the box, it looks like it's just plain and white inside, which is a little bit boring! Dig a bit deeper, and remove the cartridge, and there's something waiting for you:

Aww! An adorable little kitty! This little cat shows up throughout 13 Sentinels, with characters often fawning over its soft fur, so he gains the name "Fluffy" as a result.

We had a little hunt online to see if anyone else had managed to spot this black and white moggy hiding under their Switch cartridge, and we've got more footage of this mystery being uncovered.

Whether these two actually spotted the cat is another thing, but he was right there! We saw him! We swear. It's a pretty easy thing to miss, to be honest. If you're just a little less observant or a collector who never opens their cases, you'll never get to uncover the mystery of the cat in the box.

If you have the physical release of 13 Sentinels: Aegis Rim on Switch, go and pay your furry friend a visit. And, well, why wouldn't you have the game already? We gave it a 9 /10 in our review, and we think it's absolutely marvellous.

Are there any other fun secrets inside Switch cases you can think of? Let us know if you remember or find any!
