Buster

Buster is a robot character appearing exclusively in ''JumpStart Adventures 3rd Grade: Mystery Mountain. ''He is never named in-game, but only in the user's guide (including the digital manual). He appears in the Robot Maze activity.

Personality and characteristics
Buster does not display much personality. The manual describes him as "a bit of a stone face". Botley says, however, that Buster has "nerves of steel".

In the Game
Buster is a robot in the obstacle course. He obeys commands given by the player in order to retrieve a box in which Polly put a mission clue.

The game has robots that appear to be a palette swap of Buster who follow certain paths. They serve as obstacles and will shake up Buster if he runs into one of them.
