Plot:
Animated special about two youngsters who are miniaturized
and travel through their Uncle's body, to understand more
about his health.

Notes:
Hard to get but finally found it after 3 years.
The tape had issues as it was so old (1983?) and may have
been a rental at one time. Appears to have seen heavy use.
There is a small spot in the beginning 3rd with audi fade.
Also has line on bottom that runs constantly through.
Absolutlely no reposts. Help each other out. 10% PARs incl.

I also have the ISO as it was capped in NTSC DVD and then
authored using Canopus Procoder2 if anyone is interested.
