If/when I write a Pinky and The Brain crossover with Mina The Hollower where Pinky and The Brain are equal size to Mina, there's gonna be the reveal that Mina and Pinky are brother and sister who got separated when ACME scientists kidnapped Pinky as a baby or small child (the experiments the scientists did on him suppressed the memories of his family)
The reason I am adding this is threefold
It gives Mina and Pinky an arc that is unique to their characters.
It gives Pinky a reason to insist on going to Tenebrous Isle other than it being a potential vacation spot.
It give Mina and The Brain a clear incentive to interact since they care about the same person.
