Kinder Surprise. Chocolate hollow egg with a toy inside that once
assembled is often larger than the egg itself. Enjoyed by children all
over the civilized world where chocolate holds up. Plus, the toys are
more interesting than anything found in Cracker Jacks. Banned in the
U.S. by the Consumer Product Safety Commission, party pissers all, who
have determined you mustn't have any fun, because you know, as parents
you lack the good sense to make sure your three year old little darlings don't
stuff the toy capsules into their cookie holes and choke to death.
Therefore, to refill your supply of Kinder Surprises, they must be
procured via the internets or otherwise smuggled.

+Dr. Who, of course.
  
Tardis = time and space traveling vehicle with an alterable exterior appearance,
usually some kind of unobtrusive box like an English police call box or
a telephone booth, much larger inside than out. Here, the tardis is disguised as a Kinder Surprise egg which can go perfectly well camoflaged nearly anywhere in the galaxy except the United States.
