GULP! Inside-Body Adventure
Learn anatomy as a rice ball
Free · Designed for iPad. Not verified for macOS.
A freshly eaten rice ball travels from mouth to bottom! Dodge stomach acid, ride through heart valves and reach the brain's neurons — and learn how your body works.
Chomp, GULP! You're a rice ball that just got eaten — now journey through the human body!
Slide down from the mouth through the throat, stomach and small intestine. There you split up: Glucose rides the bloodstream to the liver, heart, lungs, kidneys, muscles and all the way to the brain's neurons, while Fiber heads through the large intestine and… out the bottom.
An action game that shows how food becomes energy for your body.
■ 15 worlds
Mouth / Throat & esophagus / Stomach / Small intestine / Large intestine to the bottom / Capillaries & portal vein / Liver / Right heart / Lungs / Left heart / Kidneys / Bladder / Muscles / Brain (special) / Neurons (special)
■ Real body science
Chomping molars, sticky saliva, a cough if you slip into the windpipe, bubbling stomach acid, peristalsis, heart valves that open with each beat, kidney filtering and reabsorption — how each organ works becomes the stage itself.
■ The human moves!
When the body's owner runs, jumps, lies down, sneezes, burps or bursts out laughing, everything inside shakes, tilts and gets blown around — and you can watch their face in a little window.
■ A twist and a boss in every world
Churn your own food in the stomach and face the Pepsin King, read the breathing rhythm in the lungs, deliver insulin keys to the muscles, tap to leap along the neuron — and outrun a very confused white blood cell!
■ Peristalsis dash and close calls
Collect nutrients to fill the gauge, then tap to dash! Skim past hazards for a "Close one!" bonus.
■ Body Encyclopedia & quizzes
Cards unlock the moment you meet an organ or nutrient (76 cards, including secret ones). After each stage a two-choice quiz earns a Professor Star, with a question to ask a grown-up at home. Jump back to any card's spot from the book.
■ Body map & Full Course
Pick worlds on a map of the body. Collect stars and badges to unlock new foods to play as (banana, sushi, bread, dumpling) and hats and glasses for the body's owner. Beat everything and run the whole body in one go on the Full Course.
■ Simple controls
Drag anywhere on the screen. Your finger never hides the character.
■ Family-friendly ads
You only see an ad if you choose "Watch to revive" after a game over. Ads are limited to general-audience content and are never personalized.
Available in English, Japanese, Spanish and Korean.
