Warning: The following article contains major spoilers for Bugsnax.

One of the most rewarding things about Bugsnax is the way it builds up to the big reveal at the end. It’s a slow burn, but keen observers will pick up on plenty of clues along the way that indicate what’s to come. Additional playthrough are sure to reveal even more hints about the true nature of Bugsnax, but as it turns out, the answer has been right in front of our faces this whole time: the Bugsnax theme song by Kero Kero Bonito not only explains the whole game, it cleverly reveals the big twist.

Bugsnax was revealed during the PS5 livestream event back in June. It was one of the most talked-about games from the event in part because the theme song is an absolute bop.

“It’s Bugsnax!” by British indie pop band Kero Kero Bonito was released as a single in July. The full 3:29 version of the song has a rap breakdown that lays out the plot of the game pretty succinctly:

That’s Bugsnax in a nutshell. The game is a journey to discover the truth about the nature of Bugsnax, but it’s also a very personal journey for the thirteen grumpuses who each traveled to Snaktooth island “seeking out a better life.”

An expedition thirteen-strong

Of Grumpuses who all set off

Seeking out a better life

On Snaktooth Island they did find

A tasty quest to fill the hole

That many feel inside their soul

Venture deep to reach the truth

And maybe you’ll learn something too

The rest of the song is the same chorus and verses we heard in that first trailer. While it may not seem like there’s anything particularly spoilery there, it turns out that the song actually reveals the secret right there in the chorus:

If you still don’t see it, it’s right there in that last line: Come to Snaktooth Island and discover its Bugsnax.

Kinda bug and kinda snack

Try to catch ’em in your trap

Feed somebody and you’ll see

We are whatever we eat

Find ’em hiding in the sand

Tearing up a ketchup patch

Come to Snaktooth Island and

Discover its Bugsnax

In the final moments of the game, it’s revealed that Snaktooth Island is bugsnax. Bugsnax are a single-celled organism — a parasite that takes over and assimilates its hosts. The entire Snaktooth island is actually one big bugsnax, and if the grumpuses hadn’t escaped in the airship, they would be too.

If you need further evidence that the lyrics reveal the secret truth about Bugsnax, consider another line: we are whatever we eat.

“You are what you eat” is a common expression, of course, but in Bugsnax it’s literal. The grumpses transform into whatever they eat. The song’s line is even more literal than it first appears though, once you know the truth about Bugsnax. Anyone who continues to eat bugsnax will eventually become bugsnax themselves. As Elizabert explains, the bugsnax change your body and your mind until you become bugsnax too. It’s less “you are what you eat” and more “what you eat becomes you.”

It was already one of the best theme songs ever, but the revelation that it holds the game’s biggest secrets takes “It’s Bugsnax!” to a whole new level.
