Once, Brendan used his powers to practice creating interdimensional portals. But the one he created was too unstable and sucked him in it. He fainted when hitting the ground after falling from the portal. When he woke up, he was trapped. After a few minutes, Bowser appeared and they talked for a bit and they noticed they both didn't want to do something against eachother. So they teamed up to find a way to get Brendan back home, and Bowser said he could stay at his castle until then.
