The document outlines the rules for a team-based game where players are split into roles to collaboratively build Lego animals. The roles are legs developer, body developer, head developer and tester. The rules describe 5 rounds of play with different collaboration restrictions for each round to encourage teamwork and test different skills. The testers use dice to introduce random defects ("bugs") and determine if completed animals pass testing or must be returned to the appropriate developer role for repairs.
