An underdeveloped bee is cast out from its hive, and soon after eaten by a bird. However, rather than the internal organs one would expect to find, the guts of the bird are facilities in which the consumed insects are brainwashed and enslaved.
- Bigger on the Inside: The bird's guts feel much larger than the bird itself.
- Brainwashing: Eaten bugs are injected with chemicals and converted into mindless drones.
- The Chosen One: The main character is called "The Hatless One" by the leader of the resistance, for being immune to the Brainwashing serum without needing a Tinfoil Hat.
- Easter Egg: There's a skull hidden (or simply hard to access) in every level, and activating them all unlocks a secret bonus.
- 11th-Hour Superpower: The protagonist spends most of the game without any means of defending itself, and the obstacles are focused on navigation and platforming. Then it picks up the cannon in the colon, allowing it to hold its own against the beefed-up security.
- The Grotesque: The protagonist, a larva with wings, is seen as this by the regular bees and quickly outcast.
- La Résistance: There's a secretive group of not-brainwashed bugs that are plotting to end the bird's tyranny by destroying missiles located in its colon.
- Multiple Endings: There are three possible outcomes, dependent on the protagonist's actions in the final room.
- Lose-Lose: The protagonist leaves the bird without launching the missiles. The resistance hangs their head in shame, and the protagonist lands on some lethal spikes on its way out.
- Going Down with the Ship: The protagonist launches the missiles, but doesn't leave the bird in time and dies in the explosion.
- The Hatless One: The protagonist launches the missile and leaves the bird before detonation. He gets out unscathed as the bird explodes.
- Red Eyes, Take Warning: Brainwashed and hostile bugs are differentiated by their glowing red eyes.
- Tempting Fate: In the Prologue, the main character cuts in front of an unemployment line for bugs, and the frustrated attendant quits on the spot and says he'd rather be stepped on than deal with this kind of disrespect any longer. Cue the bird, which steps on him before eating the other bugs.
- The Maze: The penultimate section of the small intestine is a labyrinth of passages and has multiple checkpoints where the protagonist can respawn on death, all to make it easier to get lost in.
- Tinfoil Hat: The members of La Résistance wear them to block out the brainwashing.
- Womb Level: Most of the game is set in the bird's digestive system. The environment is decidedly more mechanical than most other examples of this trope.
