When Daniel figures out how to control his shrinking, Pablo is ecstatic.
Together, they come up with a whole list of fun things to do when you're
tiny--and at the top of the list is to take a teeny tiny rocket ride. So
when Daniel joins a Model Rocket Building workshop, it's the perfect
chance. Daniel can build the rockets, launch Pablo, and then shrink down
and get into his own rocket. But when Pablo and Daniel are separated in
midair, things get sticky. Daniel lands safely next to a terrifying
sabertooth tiger fossil, but Pablo lands somewhere in the La Brea Tar
Pits. How do you find a mini-brother in a land of concrete sabertooth
tigers?
