Dr. Thaddeus Venture was invited to Brisbyland by Roy Brisby. He brought along his sons Dean and Hank, who are avid fans of Bizzy Bee and all things Brisby, but would not permit them to leave the confines of the X-1.
Dr. Venture was summoned due to Brisby's interest in gaining his cloning technology, with the meeting resulting in Brisby imprisoning Venture. Meanwhile, Dean and Hank were kidnapped by opponents of the park, the Orange County Liberation Front.
Brisbyland soon came under attack by the OCLF and Brisby was set on fire.
