“I only build in black…and white…and bamboo.”
Most believe the Panda Guy to be a simple mascot in a panda bear costume. But in times of trouble, he reveals himself as an undercover Master Builder who has sworn to free the citizens of Bricksburg from the shackles of instructions-based rules and conformity.
The Panda Guy is determined to foil Lord Business’s evil plots, although he has never succeeded so far. In his attempts to break into the Octan office tower, he hasn’t yet made it past the laser gates, let alone the sharks and the laser-sharks. Maybe the long-awaited Special will finally be the answer to completing his mission!
