Bus activities

Driver's seat

The Mouth's mini-game

• The bus rests on Arnold's tongue and can look around the entirety of the mouth. The tooth fairy^English/Ratoncito Pérez^{French, Spanish} flies around which turns a tooth into a US dollar sign^English/euro sign^{French, Spanish} when clicked. A vial of saliva floats around. There is also a toothbrush holding toothpaste that brushes whatever is in front of it when clicked.

• The player can learn about the papillae/taste buds on Arnold's tongue in a mini-game. The player feeds Arnold a certain food, which allows him to experience different taste sensations by activating certain papillae.

Back of the Bus

• The player can read various reports by other students, use the SPLAT! Backpack, and play on the minigame console.

• Clicking Ralphie's gaming console starts the Chatter Box minigame, where the player can piece together various lip flaps to see if Ms. Frizzle can correctly pronounce the selected word.
• This is one of three locations that can be used to exit Arnold's body once every area has been explored, the other two being the nose and the skin. When the player uses the mouth, Arnold coughs the bus out of his body.
