Bits

Bits are small creatures scattered throughout Planet Dob. They can be collected by using the Heart Whistle given to the player at the start of the game.

If the player makes a certain sound within the Bit's range, it will follow Dob around wherever he goes. Dob can only have 3 Bits following him at a time.

According to the original Planet Dob website, Dobtown is managed by a central "CPU", which is powered by "Bits". The bits were scattered all over the place, so the city has stopped working properly. The website also states in their description "This is BIT. BIT reacts to sound. Talk a lot with the residents of Dobtown to find out what sounds each BIT likes and what surprises you. BITs can be uploaded back to the CPU from telephone booth-like place called DTT-MS. With enough uploads, you can remix Dob Town's music."

At the beginning of the game, the only background music is a drum beat. Whenever Dob obtains a Bit, it will add a new instrument to the background music. For example, if the player collects a Bit, it may add a piano or guitar loop. The more Bits Dob obtains, the more the background music will be added upon.
