Why does Tiny the Tyrannosaur fall into line quickly after the mini-Doris is knocked off him, and why does the Robinson estate have an octopus butler? Apparently, animals on the grounds tame down quickly and get Amplified Animal Aptitude. And why would Lewis invent that? To give Franny her dream of singing frogs.
Apparently in the Bad Future, Doris did something to Goob after taking over. After a little while, the brain machine POWERS OFF like static. Who knows if the brain was just attached to the machine after Doris KILLED Goob?
