"Would you care for a Jelly Baby?"
Here we see a couple of the props for the costume -- the K-9 remote control toy dog, and genuine Jelly Babies. Both were imported from the UK. Other props not shown here are the sonic screwdriver and psychic paper.
...and before anyone starts griping about how the 4th doctor never had psychic paper, he's actually had it since his 2nd incarnation. True, in the time between the 2nd and 9th doctors he didn't really use it, but he's had it all that time, no doubt stored away somewhere on the TARDIS. :P
