Summary: The Doctor's temporary guest is causing problems.
The new temporary guest aboard the TARDIS was being an absolute pest. The Doctor had put it in the gardens where it had churned up the grass with its big feet, made a muddy wallow of the pond, uprooted trees and bushes, and eaten all the roses, and it had only been there three days!
It was a relief to know his destination was only a day or two away now and then his guest would be back home. Dinosaurs were cool, but they didn’t belong in the TARDIS any more than they belonged on any other kind of spaceship.
